Manuel Estevan Hernandez-Serrano was 18 when he was shot and killed in an alley in Aurora, Colorado, on the morning of April 28, 2017. He had been driving with an 18-year-old cousin and a 16-year-old female friend when they encountered 45-year-old auto mechanic Margarito Najera after what the teens perceived as a hand gesture. Najera accused them of speeding and burning out tires, directed them into an alley between Clinton Street and Dallas Street, and — according to witnesses — ran up to the passenger side of the Subaru and opened fire with a semi-automatic handgun.

Hernandez-Serrano was struck in the head and right arm, rushed to University Hospital, and was pronounced dead about 20 minutes later. His cousin was shot in the knee, arm, and stomach but survived. Najera was arrested at the scene; when officers asked if he had shot at the teens, he replied yeah. An Arapahoe County jury later convicted Najera of second-degree murder, attempted second-degree murder, and first-degree felony assault in connection with these shootings.

Does anyone have information about the early-morning confrontation on East 14th Avenue or the alley between Clinton and Dallas Streets?
