Police in Howard County, Md. announced Thursday that the body of a woman who went missing in 1991 was discovered underneath a shed on the property of her husband, who has been arrested and charged with first- and second-degree murder.

Robert Jarrett, of Elkridge, is accused of killing his wife, Christine, after the couple had an argument in their home in January 1991, the Howard County Police Department said in a press release. Investigators visited the home—which is now occupied by Robert Jarrett’s second wife, from whom he is estranged—on a recent tip that further suggested the possibility that Christine Jarrett’s death involved foul play.

Jarrett’s current wife allowed investigators to search the property, and a body was found buried in concrete underneath the shed’s floorboards, police said. The remains have not yet been examined, but personal effects found on the body suggest it is that of Christine Jarrett.

Jarrett was 34 years old when she disappeared in 1991 and stormed out of her home after an argument with Robert, according to The Doe Network, which tracks missing persons cases. The couple had two children, then ages five and 10, and Jarrett left their home on Claire Drive between 10 p.m. and midnight the night of January 3. It is believed she was carrying $4,000 in cash, according to The Doe Network.

Robert Jarrett reported his wife missing a few days later, and while police suspected foul play was involved in the disappearance, they lacked until now sufficient evidence. Christine Jarrett was declared dead in January 1998.

Robert Jarrett is being held without bond at the Howard County Detention Center without bond, Elkridge Patch reported.
