Police: Child discovered murdered mom's body

Posted: Updated:
McKINNEY, Texas -

A child's grim discovery led police to a McKinney home on Wednesday for a murder investigation.

Detectives also found a note on the coffee table with handwritten and typed information about what happened inside the house.

McKinney police said it was a neighbor who called 911 for help for Mary Beth Merz's daughter. The child got home from school but couldn't get into the house. Police records state pillows were stacked against the window to block the view but the child could still see her mother lying unconscious.

Police said Mary Beth Merz had been shot at least twice with shell casings on the floor. Her husband, 42-year-old Eric Merz, was also found unresponsive on the floor of his study.

According to an arrest warrant affidavit, he had taken hydrocodone and appeared to be asleep. He was wearing a brown leather holster with a loaded semi-automatic pistol and was within reach of a loaded AR-15.

He also had a contusion on the corner of his right eye, red marks on his chest and blood on his left sock, the affidavit said.

Merz was taken to the hospital and then released and charged with his wife's murder. He is being held on $150,000 bond.

Police have still not said whether this was an attempted murder-suicide or why investigators were searching a fire pit outside the couple's home. However, the search warrant references a note that was found on the couple's coffee table.

There have been no reports of any recent violence at the home, but court records show Merz was arrested in San Antonio 12 years ago for domestic violence.
