Ramon Delgado Jr., 28, was killed during a party in the 2400 block of South Ninth Street in southeast Fresno on May 23, 2015. The gathering turned violent during a confrontation between partygoers and members of the Bulldog gang; gunfire during the altercation killed Delgado and 27-year-old Rene Diaz and wounded three other people, including the suspected shooter, Conrad Daniel Serna.

Fresno police investigated the double homicide and arrested Serna at his home on June 2, 2015, charging him with two counts of murder. Investigators reported that Serna and another man were involved in a fight with several attendees before Serna drew a firearm and opened fire; Serna was also shot during the incident, reportedly by someone with Diaz and Delgado.

Delgado left behind three children and was described by family as a devoted father and friend. Detectives continued to interview witnesses and seek any additional suspects or motives. Did anyone at the party or in southeast Fresno on May 23, 2015, see what happened that night?
