A cleaning woman stole a diamond engagement ring from a 90-year-old woman, St. Louis County Police said. The ring originally belonged to the elderly woman’s mother.

The St. Louis County Prosecuting Attorney’s Office issued warrants Oct. 8 on Angela M. Wisecarver, 31, of the 3100 block of Quiet Forest in Jefferson County for one count of felony stealing.

Prosecutors said Wisecarver stole a 90-year-old woman’s diamond engagement ring, which originally belonged to her mother. The bond has been set at $7,500.

St. Louis County Police Central County Precinct officers responded July 26 to a theft in the 1200 block of Moncoeur Drive in unincorporated St. Louis County just north of Creve Coeur.

The elderly woman reported her deceased mother’s diamond engagement ring had been stolen from her bedroom sometime July 24. The victim said she had been home the entire day, but the staff from the cleaning company she owns had cleaned her home.

Police said the ring was valued at $5,000, but was invaluable to the owner.

An investigation, aided by Executive Cleaning Service, discovered that Wisecarver cleaned the residence and then immediately pawned the ring at a jewelry shop in Crestwood, police said. She was a new company employee.

“We don’t often have the chance to feel rewarded by our work,” said St. Louis County Police Chief Tim Fitch. “This case definitely offered that opportunity. She was so happy when we returned that priceless ring back to her, and I know we were as well. Our officers and detectives did a fantastic job.”
