Police have identified the man and woman found dead Wednesday in a Mounds View home as Mark Schnor, 47, and his wife, Christine Schnor, 39.

Each suffered a single gunshot wound to the head, according to Mounds View Police Chief Thomas Kinney. A handgun was found at the scene.

Authorities did not officially declare the deaths a murder-suicide, as a medical examiner's report won't be complete for several weeks because of pending toxicology tests. However, Kinney said, "It is consistent with that scenario."

Evidence suggests that Mark Schnor was the shooter, Kinney said. No note was found, so it's unclear whether Christine Schnor was a willing participant, the chief said.

"We are unable to determine that at this stage, and maybe we'll never know for sure," he said.

Police are investigating whether any electronic notes or messages might have been left.

The couple were found in their bed, which was in the living room. Shades were drawn, so when relatives went to check on the couple's welfare Wednesday they had to call police to gain entry into the home in the 2900 block of County Road 10.

Relatives had not heard from the couple for about a week. It's unclear how long they may have been dead.

Kinney said relatives reported that both Mark and Christine Schnor had health issues, including depression, and that they had been struggling financially.

There was no history of police calls to the address aside from a medical call last year, Kinney said.
