Rothwell, 31, confessed to killing his wife, Jennifer Rothwell while denying the killing was premeditated and seeking a conviction on a lesser manslaughter count during his trial. The Creve Coeur resident testified that he clubbed his 28-year-old wife of four years to death with a mallet at their home in November 2019, during a heated argument over his affair with another woman.

Her badly beaten body was found about a week after she was reported missing. Beau Rothwell is set to be sentenced July 8, when he faces life in prison without the possibility of parole.

Prosecutors portrayed as a careful planner, revealing the jury his texts with the other woman, as well as a list of pros and cons he drafted for leaving his wife. He had reported his wife missing on Nov. 12, 2019.

Previously, police said Rothwell was caught on video buying cleaning products — including bleach and gloves — one day before she vanished.

Investigators determined the blood was his wife’s.

Jennifer Rothwell had previously searched “what to do if your husband is upset you are pregnant” on her phone before she went missing, police said.

Her body was found about 45 miles northwest of her home.

Rothwell was arrested just hours after posting a plea for help on social media.

“Some of you may have heard already, but last night my wife Jennifer went missing,” he wrote on Facebook. “I’ve filed a police report and the search is ongoing. Please, if you hear of anything or have any information it would be greatly appreciated.”

Initially, he was arrested in 2019 on evidence tampering charges, but charges were upgraded to murder after investigators used DNA samples from Jennifer’s parents to confirm blood found inside the home was hers.
