WAUPUN, Wis. (WTAQ) - A former Racine County man who kidnapped and attacked his ex-wife six years ago tried to escape from the state prison in Waupun.

Corrections officials said they uncovered what they called a “complex escape plan” by David Larson. And they thwarted it last Saturday, with the help of 3 area law enforcement agencies.

Officials did not release other details. But the victim, Teri Jendusa-Nicolai, told the Racine Journal Times that Larson was apparently trying to fake a medical emergency – and authorities knew right away it was a hoax.

Dodge County sheriff’s deputies are still investigating the incident, and will decide if new charges will be sought. Larson is serving a 35 year prison term for attempted homicide. He’s also been sentenced to life in a federal prison for kidnapping.

Authorities said he lured his ex-wife Teri Jendusa-Nicolai into his home in January of 2004. He beat with her with a baseball bat, and left her for dead in a trash can in a cold storage bin near Chicago, close to where he worked. She lost the baby she was carrying, and part of a foot was amputated because it froze.

Jendusa-Nicolai said the escape attempt did not surprise her. She told the Racine paper that Larson is getting desperate after losing a federal appeal of his life sentence.
