On the evening of Tuesday, October 20, 2015, in Auburn, Washington, Mark Rivera, 40, and his 19-year-old stepson, Angel Mireles, were waiting at a bus shelter after leaving a nearby friend’s home. A dark-colored Acura pulled up shortly after 5 p.m.; words were exchanged between Mireles and the car’s occupants, then gunfire erupted from the vehicle. Mireles was killed at the scene. Rivera ran to help his stepson and was shot; he was taken to a nearby hospital in critical condition and died the following afternoon. Rivera’s 13-year-old son was present and escaped unharmed.

Investigators linked a stolen vehicle matching the description to the shooting and used convenience store surveillance footage to identify a suspect. Police arrested 19-year-old Froilan Hermenegildo, described as a member of a street gang; he was charged with two counts of second-degree murder, first-degree assault, unlawful possession of a firearm, and possession of a stolen vehicle, with bail set at $2 million. A 16-year-old girl believed to have been in the car was charged with rendering criminal assistance. Police said the victims were not believed to be involved in gang activity.

If anyone witnessed the shooting or has information about the vehicle or its occupants, please share what was seen or heard.
