Joel David Vargas, 19, of Stockton, California, was shot while attending a party on Paloma Avenue on July 20, 2019 and died early the next morning at San Joaquin General Hospital. He had recently graduated from Cesar Chavez High School and was employed as a machine operator at O-G Packing. Family remembered him as a devoted son and brother, generous and always smiling; they said he had no known enemies and had never been in fights.

The party where Joel was shot drew more than 100 people on a normally quiet street. Despite the crowd, initial investigators struggled to identify who fired the shot. In the weeks after the killing, authorities arrested a 17-year-old and booked the juvenile into Peterson Juvenile Hall; detectives continued interviewing witnesses and collecting evidence.

Does anyone who attended that party or lived on Paloma Avenue that night have information that could help complete the timeline or identify what led to the shooting?
