TROY, Mo. — The remains found near Cuivre River State Park were positively identified as those of Jennifer Rothwell, the St. Louis County woman whose husband is charged with killing her.

St. Louis County police confirmed the identity on Wednesday. 

The woman's husband, Beau Rothwell, and his attorney, Charles Barberio, met with detectives Monday and Rothwell told them where they could find his wife's remains, police said.

Detectives searched a four-mile stretch of Highway 61 in Troy for about six hours before finding the body about 20 yards off the shoulder in a wooded area. 

Police have said that detectives are unaware of any connection Beau Rothwell had to the area where he allegedly put his wife’s remains.

St. Louis County Prosecutor Wesley Bell said Monday that authorities do not have any information regarding “the how or the why, yet,” in the case.

Police believe Beau Rothwell, 28, killed his wife sometime on Nov. 11. He was seen on surveillance video that day buying bleach and other cleaning supplies at a local store. He reported her missing the next day, saying he had last seen her leaving for work that morning.

Her car was abandoned near Fee Fee Road and Olive Boulevard, about 1½ miles from her home on Northwinds Drive.

In court documents, police said they found multiple bottles of bleach inside the couple’s home just north of Creve Coeur, along with a wet carpet and blood-stained carpet and padding.

St. Louis County police said they used DNA samples from Jennifer Rothwell’s parents to confirm that blood found inside the Rothwells’ house was their daughter’s.

Jennifer and Beau Rothwell earned degrees in chemical engineering from the University of Missouri-Columbia in 2013. The couple married in 2015 in St. Louis County.

Jennifer Rothwell, 28, had been a chemical engineer since July 2013 for MECS Inc., once a subsidiary of Monsanto that was purchased by the DuPont chemical company in 2010.
