CRESCENT, Okla.– After an investigation into a suspected robbery and homicide, authorities have arrested a Logan County man for the murder of his wife.

The Logan County Sheriff’s Office requested help from the Oklahoma State Bureau of Investigation to help deputies look into a home invasion that happened in Crescent Wednesday afternoon.

After receiving a call from the 500 block of Ruth Ln., deputies arrived to find 49-year-old Monica Schemm dead inside her home. Her hands were bound with zip ties and a plastic bag was taped around her head with duct tape.

Her husband, 52-year-old Mark Alan Schemm, had been bound with zip ties and a plastic bag placed over his head.

He was able to create a hole in the bag by biting it.

Their son found the couple when he returned home from work and called police.

Initially, Mark Schemm told agents that two Hispanic men broke into the home, tied him and his wife up, put plastic bags over their heads and robbed them.

Later in the evening, he admitted to killing his wife and fabricating the home invasion story.

“There’s no way for us to verify that, we don’t have any calls or records showing that it was reported to our agency,” said Capt. Rich Stephens with Logan County Sheriff.

Agents say the stolen goods Schemm initially told them were stolen during the home invasion were recovered from a place he told them about.

Schemm is facing a first degree murder charge. Schemm claimed his wife suffered from a brain tumor that left her severely handicapped.

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

Schemm was arrested for first-degree murder and booked into the Logan County Jail.
