A missing mother’s body was found entombed in a Prince George’s County home, and her boyfriend has been charged with murder.

Alexis Schuler, 29, was reported missing to D.C. police last week. On Sunday, Prince George’s County police executed a search warrant at the home of 30-year-old Devontae Gray in the 700 block of Larchmont Avenue in Capitol Heights.

Police found Schuler’s body in a makeshift tomb under the stairs of the home, according to charging documents.

Her body was in a bin that was wrapped in plastic. Gray poured concrete around the bin, placed drywall around it and laid faux bricks on the drywall, investigators. Schuler was found under a large amount of soil and hay.

Gray, who is the father of one of Schuler’s children, initially denied involvement but then confessed to the crime, allegedly saying he killed her during a dispute, police said.
