The killing of a 17-year-old Colorado Springs boy, for which another teenager is being sought, apparently was an accident, according to a longtime friend of both the victim and shooter.

Marshall Aaron Mitschelen was killed Wednesday at his home in the 2900 block of Whileaway Circle, police said. A 17-year-old boy is being sought in the death on suspicion of manslaughter, a felony.

The suspect's name has not been released by police because of his age.

Ian Sikes, 18, who witnessed the shooting, said a group of friends had gathered at the home, where Mitschelen lives with his father since his mother passed away in August.

One of them brought a gun, which went off, the bullet hitting Mitschelen in the face, Sikes said.

Officers went to the area shortly before 9 a.m. for a reported shooting and found Mitschelen dead, police said. Officers initially believed the gunshot wound was self-inflicted. The suspect fled before officers arrived.

Sikes said he had known Mitschelen for about eight years. They used to live in the same neighborhood and grew up together, he said.

When he thinks of Mitschelen, he recalls "positive vibes" and the boy's love of video games.

"Everyone should remember him for who he was, not this," Sikes said.

Mitschelen was a former School District 11 student, said spokeswoman Devra Ashby. He last was enrolled in November at the Tesla Educational Opportunity School and the Achieve Online School.

Police on Thursday also identified a victim who was found dead Sunday after a reported shooting.

The body of Richard Paul Martinez, 40, of Colorado Springs, was found at a storage facility near Hancock Expressway and South Academy Boulevard police said.

Martinez was found after police received a report of a shooting at the Angry Pirate Bar, 2100 E. Platte Ave., about 8:40 p.m. Further investigation led them to the storage facility about five miles away in the 3400 block of Astrozon Court, where they found Martinez, "who had suffered apparent trauma," police said.

No arrests had been announced.

The deaths are being investigated as the city's 13th and 14th homicides this year. At this time last year, there were 13 homicides.

Anyone with information is asked to call police at 444-7000. To remain anonymous, call the Crime Stoppers Tip Line at 634-7867 or 1-800-222-8477.
