Wichita police say they have arrested two people in connection with the deaths of a Wichita couple.

A 19-year-old man was arrested Monday afternoon and booked into the Sedgwick County jail on suspicion of two counts of first-degree murder and other charges.

A 17-year-old suspect was arrested Monday morning and is being held in a juvenile detention center.

They are suspects in the deaths of 70-year-old Martha Moreno and her husband, 72-year-old Godofredo Moreno, whose bodies were found in their home Thursday. Police originally said the victims apparently died of stab wounds but Lt. Todd Ojile said Tuesday they died of gunshot wounds.

Ojile says the suspects knew one of the couple’s children and both have criminal histories.

He says robbery was the apparent motive for the crime.
