Marcus Pedro Cisneros-Lopez was 19 when he was shot dead on February 16, 2015, outside a Whataburger on the Northeast Side of San Antonio. He had been born August 20, 1995, attended Madison High School, was a member of St. Helena’s Catholic Church and enjoyed music.

Police say Marcus and a female companion had driven to meet people to sell marijuana. According to reports, the meeting turned violent when one suspect produced a gun and demanded their belongings; as Marcus and his companion tried to flee, the suspect opened fire, striking Marcus multiple times.

San Antonio police arrested three men—Shawn Dillard, Paul Lopez, and Xavier Gonzalez, then ages 18 or 19—on capital murder charges. Shawn Dillard later pleaded guilty and agreed to cooperate with prosecutors, with a sentence that makes him eligible for parole only after at least 22 years.

Did anyone who knew Marcus or who was in that area that night see or hear anything that could help the case?
