A Columbia County man accused of killing his girlfriend and staging her death to look like a suicide has been found not guilty.

Traci Rataczak was found dead in her home in 2013. Her boyfriend, Patrick Kraemer claimed she killed herself. A heart monitor she was wearing at the time she died made investigators believe she was killed. He was arrested in September 2014 for her murder.

The jury returned a not guilty verdict at 7:21 p.m. Thursday after a 10-day trial. Kraemer has been released from jail.
