Mark Jasper, a 64-year-old retired Davenport firefighter and veteran, was found dead at his Ripley Street home on the evening of January 7, 2017. Police discovered he had sustained a fatal gunshot wound after responding to the residence about 10 p.m. He had served the city from 1994 to 2011 and previously served in the U.S. Marine Corps in Vietnam and the U.S. Navy Reserves; he is remembered as a father and grandfather.

Investigators focused on his wife, 52-year-old Shiela Jasper. According to the criminal complaint, she admitted retrieving a revolver and shooting Mark while he was asleep in a chair, then covering his face with a towel and waiting several hours before contacting a mortuary. She was arrested and charged with first-degree murder and booked into the Scott County Jail with bond set at $1 million. The motive has not been released.

Did anyone in the Davenport area see or hear anything that night or have information about the couple that could help explain what led to this killing?
