Forensic tests confirmed that a Silver Spring man shot and killed a Highland woman and then shot himself in the back of the head, Howard County police said yesterday.
Police said the weapon, a 9 mm pistol, was owned by Robert Warren Harris, 44, and gunshot residue was found on his hands. Police suspected a murder-suicide when they found the bodies of Harris and a former girlfriend, Ellie Kasten, 37, in her bedroom July 17.
