Beau Rothwell was spotted Monday on video buying cleaning products, including bleach, carpet cleaner, and gloves, according to the probable cause statement, which police cited in a news release.
His wife was reported missing Tuesday, and her car was found abandoned less than 2 miles away later that day. On Facebook, Beau posted that his wife was missing and added that he had filed a police report.


Rothwell, 28, is being held in jail on $100,000 bond on the felony after being charged Thursday. St. Louis County police are investigating the disappearance of his wife, Jennifer Rothwell, who is a chemical engineer, as a homicide, although her body hasn’t been found. It wasn’t immediately known if he has a lawyer.
Police said on Thursday morning said that they are applying for charges of first-degree murder and tampering with physical evidence.

Before Beau Rothwell’s arrest, he posted on Facebook, asking for help in the search for his missing wife. ‘Some of you may have heard already, but last night my wife Jennifer went missing,’ the post said. ‘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,’ he wrote.
Jennifer Rothwell, 28, was reported missing on Tuesday. An engineer for DuPont, she didn’t show up for work that day and family and friends who were used to hearing from her every day couldn’t reach here. Police later discovered her abandoned Hyundai Sonata near the intersection of Olive Boulevard and Fee Fee Street, less than two miles from the Rothwell’s house northwest of Creve Coeur.

As the search continued for Jennifer Rothwell, officers were scouring a wooded area Thursday in between where her car was found and where she lives.


Jennifer Rothwell’s family is offering a $25,000 reward for any information that leads to her whereabouts. Her mother, Robin von Hausen, said her daughter had just moved to western St. Louis county with her husband and worked at DuPont.
Von Hausen said it was one of her DuPont co-workers who tipped them off that something might have happened.
‘A co-worker texted and said, `Hey, how is Jennifer?´ They assumed she just hadn’t come into work because of the weather or whatnot,’ von Hausen said.
