UPDATED Saturday December 29, 2012 --- 7:07 p.m.

From the Madison Police Department and US Marshals:

An extensive two and a half year investigation by U.S. Marshals, Madison Police and the Dane County District Attorney's Office resulted in the December 28th arrest of Arain Gutierrez. Gutierrez AKA Ivan Mateo-Lozenzo is charged with the April 28th, 2010, shooting death of 19 year-old Antonio Perez in the parking lot at Webcrafters on Fordem Avenue in Madison.

An Investigation after the shooting resulted in the immediate arrest of three suspects. Gutierrez and Billy Wenner-Say were able to elude arrest and flee the Madison area. U.S. Marshals and Madison Police believed both fled to their home countries,Gutierrez to Mexico and Wenner-Say to Guatemala.

In the two and a half years that followed US Marshals in Madison and San Diego and Madison Police worked together to develop information as to both subjects location. Within the last six months, investigation showed Gutierrez in Cancun, Mexico. During that time the Dane County District Attorney's Office provided the necessary legal support for Gutierrez international arrest warrant.

Within the past month U.S. Marshals, Madison Police and Mexican authorities narrowed the information to a specific address in Cancun. On December 28th at 9:30 p.m., Cancun time, Mexican authorities arrested Gutierrez.

The Madison Police Department released the following statement:

"This type of senseless gang violence will not be tolerated in the City of Madison, and for more than 2 1/2 years the Madison Police Department has been working diligently and cooperatively with the U.S. Marshals Service, and the Dane County District Attorney, to make sure this fugitive did not escape justice. This case demonstrates, again, the strong relationship that exists between the MPD and U.S. Marshals."

Gutierrez will be transported to Mexico City, where he will await extradition.

MADISON, Wis. (AP) -- A fifth person has been charged in last week's apparent gang-related killing of a Madison 19-year-old.

A 15-year-old Madison boy was added as the fifth defendant in the case on Wednesday.

Authorities say the group had gone out last week looking for rival gang members when they saw Antonio Perez taking a break from his job at Webcrafters.

The criminal complaint says the group confronted Perez about his gang affiliation, then shot him after learning he was a member of the Clanton 14, or C14 gang.

The Wisconsin State Journal reports that U.S. Marshals in Texas continued to look for the alleged gunman, 21-year-old Ivan Mateo-Lozenzo. Another man also remained at-large on Wednesday.

Madison: Prosecutors asked for high cash bond for the two murder suspects, saying they were likely to flee the state or the country. The Court agreed, setting bond for each at $200,000 cash.

Two of the five suspects in last Wednesday's homicide made an initial appearance in Dane County Court Tuesday.

19-year-old Karen Giron-Cruz and 16-year-old Victor Prado-Velasquez are each charged with being party to the crime of first degree intentional homicide, for the shooting death of Antonio Perez.

Two other suspects, 23-year-old Billy Wenner-Say and Ivan Mateo-Lozenzo (aka Arian Gutierrez) are also charged but have not been caught. "We have credible information to believe that they have, may have, or are in the process of fleeing the country," says Corey Stephan, Dane County Asst. District Attorney.

Police only know the fifth suspect as Luis or Sleepy.

According to the criminal complaint, last Wednesday night, the five suspects piled into a small white car and went driving around Madison. "They were specifically going out and looking for rival gang members," says Stephan.

Stephan says as they drove by Webcrafters on the north side, they saw 19-year-old Antonio Perez in the parking lot. "Defendant Ivan Mateo-Lozenzo, who we believe is the shooter, said, 'Hey, that's Little Puppet,' indicating the victim's street name, 'Pull in.'"

The four male suspects confronted Perez and two co-workers who were on a break. Witnesses told police the suspects kept asking if they were part of a gang. "The gun was pointed at one of them and then the next one. What do you claim, what do you claim?" says Stephan.

The co-workers were not part of a gang, but the suspects knew Antonio was part of the Clanton 14 Street gang, or C-14. By then, Karen Giron-Cruz had turned the car around for a faster getaway. "That's when Ivan Mateo-Lozenzo shot him," says Stephan. "This defendant indicates that she heard that shot, looked over and saw him holding the gun, saw the victim run and fall."

Antonio Perez was prounced dead at the hospital. Family members were in court, but had no comment.


UPDATED Tuesday, May 4, 2010 --- 2:54 p.m.

At his initial appearance in court today, 16-year-old Victor Prado-Velasquez spoke through an interpreter. The judge set bail at $200,000 cash. The District Attorney's Office recommended a high amount because they believe if Prado-Velasquez is out of jail, he may flee to Mexico. The DA also believes the two men at large for the murder, Arain Gutierez and Billy Wenner Say, have already fled or are in the process of fleeing to Mexico.

Prado-Velasquez is originally from Riverside, CA. He moved to Wisconsin last September, and enrolled at Verona High School in November. The DA says he is unemployed, and has no connections to the community. No family members of Prado-Velasquez were at the hearing.


UPDATED Tuesday, May 4, 2010 --- 2:40 p.m.

At her initial appearance, Karen Giron-Cruz spoke through an interpreter, and like her co-defendant, had bail set at $200,000 cash.

Giron-Cruz's parents were there at their daughter's hearing. NBC 15's Zac Schultz spoke to them briefly. They tell him they own their own home, and have been living in the United States for the past decade, after moving from Mexico City. They say their daughter has been in the US for six years.

There were also a number of family members of the victim, Antonio Perez, at the court appearance. They had no comment for reporters.


UPDATED Tuesday, May 4, 2010 --- 2:14 p.m.

Two people appeared in court this afternoon in connection with last Wednesday's murder of 19-year-old Antonio Perez.

Karen Giron-Cruz and 16-year-old Victor Prado-Velasquez made their initial appearances today. Still at large are Arain Gutierez and Billy Wenner Say. According to the criminal complaint, all four are charged with First Degree Intentional Homicide-Party to a crime. A fifth person is also being sought, though authorities have not yet made contact with him, and Madison Police say they have not yet positively identified him.

The complaint says all five people were in the car the night of the shooting. It says the five decided to drive around looking for rival gang members from the Clanton 14 Gang, also known as C-14. One of the people in the car knew Antonio Perez worked at Webcrafters on Madison's east side. When they drove by, they saw Perez standing outside the building with two others. The four males got out of the car and approached the threesome. Karen Giron-Cruz got behind the wheel and positioned the car for a getaway.

The complaint says when the four from the car approached the three Webcrafters workers, they asked if the workers were gang members. All three men denied being in a gang. Then Arain Gutierez pointed to Perez and accused him of being a member of C-14. According to one account, Gutierez knew Perez as "Little Puppet" and had been in a fight with him previously. According to Prado-Velasquez and Giron-Cruz, Guteirez pulled out a gun and shot Perez multiple times. Perez was taken to a hospital where he died.

The complaint says both Prado-Velasquez and Giron-Cruz thought they were just going to get into a fight with the group, and were shocked when Guteirez shot Perez.


UPDATED Tuesday, May 4, 2010 --- 12:40 p.m.

Below is the message sent to parents and staff yesterday afternoon from the Middleton-Cross Plains Area School District:

The increased security measures put in place last Friday at Middleton High School will continue for now. These measures are still considered precautionary as we have not received any specific information to indicate a threat exists at MHS.

A warrant has been issued for Arain Gutierrez, a MHS student, for his possible involvement in last week's gang-related homicide in Madison. Although police feel it is highly unlikely that he would show up at MHS, we will maintain an elevated level of security at the high school for the time being.

For now, students may exit from any door, but must return to school through the Greeter's Station at the main entrance of the school. All other doors will be monitored and used for exit only. The Middleton Police Department will continue to provide extra patrol around the school and will be as visible as possible. In the unlikely event we receive information from the police that warrants more serious security measures, we will inform you as soon as possible.

The security of our schools is our highest priority. We will continue to take all measures to ensure the safety of our students and staff.

Tonight Madison Police are one step closer to catching a murderer.

They have the getaway vehicle in their custody but say the suspected gunman is still at large.

Neighbors say police have been staking out a south Madison neighborhood ever since a 19-year-old man was shot and killed on the north side Wednesday night. Today they made their move.

For two days Madison Police have been searching for the white car last seen leaving the murder scene and when police moved in to seize it today they did it with force.

Neighbor Rochel Johnson says, "I know something is going down and then sure enough three minutes later the SWAT team pulls in in their black truck and they had the microphone out and were telling everyone in the residence to get out."

Around noon police executed a search warrant at a home on the 1700 block of Baird Street.

Dave Fulbright who lives down the street says, "I'm surprised it's so close to home for sure, definitely. It's a little worrisome from a kid standpoint."

19-year-old Antonio Perez had just stepped outside of work Wednesday night to take a break when he was shot and killed.

Ever since police have been checking into many leads and have a number of people they want to speak with.

One of the them, a female associated with the white car, was being interviewed into the evening.

While police spent several hours going through the house on Baird Street, it's obvious they still want to take a much closer look at the vehicle.

It has been seized by police.

Now the hunt continues to find 4 Latino males, one of them is identified in a police sketch and is the suspected shooter.

Fulbright says, "We kind of knew maybe they were looking for that guy in the neighborhood but we didn't know it was so close."

In fact one neighbor says she is positive she has actually seen a man matching the suspect sketch in the car that was seized.

Madison Police say they continue to worry tonight about possible retaliatory acts of violence because they think this is a gang on gang crime

They urge anyone with information to call Crime Stoppers at 266-6014.

For almost a decade the Madison Police Department has used Spanish language broadcasts to help them break down cultural and language barriers.

Following Wednesday night's deadly shooting they did it again.

Calling on members of the Latino community to come forward with information about the murder.

Late Wednesday night shots rang out on Fordem Avenue and a 19-year-old male lost his life. Less than 24-hours later, everything seems to be back to normal at least on Madison's north side. But at La Movida--a Spanish language radio station in Madison-they break from the norm.

Today, DJ Diego Campoverde mixes in an interview with a detective from the Madison Police Department. They are trying to get listeners in the Latino community to come forward with information about the murder and ease fears about police.

Detective Rosa Aguilu says, " Our department, and I have to stress this, the policy is that we do not ask people what their legal status in the country is. When we come to them, we come to them because they need our assistance they need our help regardless of who they are or where they come from. "

This isn't the first time MPD and the station have teamed-up. In the past the partnership has led to tips and helped eliminate the us versus them mentality.

Diego Campoverde says, " We are always afraid of the police. We have that idea. But it's not like that. We have...I think broke down this barrier of the police department and the citizens in general. "

No tips were reported right after the interview but we were told it might take a while but they're sure they will come.

La Movida's Lupita Montoto says, " Right now it's more confident for Latinos to make a phone call and report any issue that is going on out there. "

The race is on to find a wanted murderer before any more lives are lost in retaliation.

A 19-year-old man is dead after a shooting on Madison's northside and police say it's gang related.

Tonight, they worry it could be a sign of things to come.

Police say a 19-year old man was only trying to do his job when his past caught up to him.

Just before ten o'clock last night a car filled with 4 men and one woman drove past a business in the 2100 block of Fordem Avenue and one of them started shooting, killing a man standing outside.

Madison Police Public Information Officer Joel DeSpain says, "Based on what we are hearing from citizens it is likely that they were members of another gang, a different gang than his that may be responsible for this crime."

According to employees in the building the victim had just stepped outside on a break and there were other employees with him when someone opened fire.

Family members identify that victim as Antonio Perez and while police say this shooting was gang related and was not random neighbors were immediately shaken up.

Neighbor Omar Zguerdoufi says, "I never see something like this. Usually I see police pulling someone over for something like speeding or something like that."

Less than 24 hours later there is no sign of the shooting but police worry about what could still be coming.

DeSpain says, "Any time we have gang violence there is always the possibility that there could be retaliation, retribution."

Late this afternoon police released a sketch of the suspected gunman described as a white Latino male, approximately five feet eight inches tall and 175 pounds.

Police believe he is in a rival gang, part of a growing problem in Madison.

Police say there are 900 confirmed gang members in Madison and at least 600 associates. Some of the gang members tell them the numbers are closer to 2,500 operating 40 to 60 gang groups.

It's a problem that if ignored, could continue to claim victims.

We talked to one family member tonight who is pleading with anyone who has information to contact police. She says until the person responsible is caught, her family will have no closure.
