CRESCENT — Oklahoma State Bureau of Investigation agents have arrested a Crescent man on a murder complaint, a spokeswoman said.

Jessica Brown said the Logan County Sheriff’s Office requested OSBI assistance with an alleged home invasion robbery and homicide that occurred in Crescent Wednesday afternoon.

A 911 call was made from 560 Ruth Lane in Crescent at 6:15 p.m., Brown said.

When deputies arrived at the home, they found Monica Schemm, 49, dead inside her bedroom, Brown said. Her hands were bound with zip ties and a plastic bag was secured around her head with duct tape, Brown said.

Her husband, Mark Alan Schemm, 52, had been bound with zip ties and a plastic bag placed around his head, Brown said. He was able to create a hole in the bag by biting it, Brown said. Their son, who also lived at the home, found the scene when he returned from work and made the emergency call, she said.

OSBI agents took Mark Schemm to the sheriff’s office to interview him, Brown said.

Initially, he told agents two Hispanic males had broken into the home, tied up him and his wife, put plastic bags over their heads and robbed them. He said he was able to puncture the plastic bag to breathe, Brown said.

Later in the evening, Schemm admitted to killing his wife and fabricating the home invasion story, Brown said. Schemm said his wife suffered from a brain tumor and fall that had left her severely handicapped.

“He said his wife repeatedly asked him to kill her as her attempts to commit suicide were futile,” Brown said.

Agents found jewelry reported to have been stolen in the home invasion and items used in the crime at a location disclosed by Schemm, Brown said. After the interview and admission, OSBI agents arrested Schemm for first degree murder, Brown said. He was booked into the Logan County jail.

On Thursday, the Logan County District Attorney’s Office filed a first-degree murder charge in district court, records show. | 341-2121, ext. 108
