Giovanni Galindo, 24, of Chicago was shot to death on September 5, 2014, at his home in the 6200 block of South Kilpatrick Avenue during a marijuana transaction that went wrong. He was found in the stairway leading to the basement from the outside of the house, with a shattered jar of high-quality marijuana nearby. Witnesses heard three to four shots and saw two men running from the backyard; Giovanni was pronounced dead at 5:18 p.m. by the medical examiner’s office.

Police say Pedro Corral, then 16, arranged the meeting under the pretense of buying marijuana and, with co-defendant Luis Alfaro, intended to rob Giovanni. Corral allegedly produced a semi-automatic handgun, shot Giovanni several times, and fled with the marijuana. Corral was charged with first-degree murder and held without bail; Alfaro was also charged and held in lieu of $1 million bail. A third suspect, Anthony Guedes, was extradited from Kissimmee, Florida and identified as a participant; he was found with a gunshot wound to the head. Giovanni was a young father of two.

Does anyone have details about the people who were seen running from the backyard or other witnesses to the shooting?
