Paul Guzman, 39 and a resident of Santa Ana, California, was shot and killed on April 8, 2015. The shooting happened about 2:30 p.m. after Adan Rodriguez Leon, identified as the brother of Guzman’s girlfriend, approached Guzman at his home. The two walked down the sidewalk together and Leon produced a loaded firearm and shot Guzman multiple times, then fled the scene, leaving Guzman fatally wounded.

The Santa Ana Police Department responded and obtained an arrest warrant the same day. Leon was detained in Mexico on April 10 and taken into SAPD custody on April 12, 2015. He was charged with one felony count of first-degree murder and a sentencing enhancement for personally discharging a firearm causing death was alleged and later found to be true. A jury found Leon guilty at trial on February 9, 2017.

What details about Guzman’s life or the events that afternoon might help explain how this confrontation began?
