MADISON, Wis. (AP) -- A state appeals court says a man accused of opening fire on Forest County Sheriff's deputies in 1999 was properly convicted.

A judge sentenced Robert Jacobsen in 2001 to 36 years in prison. Jacobsen, now 31, has mounted a number of unsuccessful appeals since then. He raised multiple issues in his latest attempt, including contentions that prosecutors didn't have enough evidence to convict him and they failed to correct false testimony implicating him.

The 3rd District Court of Appeals rejected all his arguments Wednesday. The court said Jacobsen should have raised his evidence issues years ago and his trial attorney decided to attack the testimony during cross-examination.

Jacobsen's appellate attorney, Robert Henak, says he's disappointed and may ask the state Supreme Court to take the case.
