On October 28, 2023, a tragic shooting occurred at a house party in San Antonio, Texas, resulting in the deaths of 40-year-old Marvin Medrano and 30-year-old Jennifer "Jenny" Colin. The incident took place in the 300 block of Roslyn Avenue on the city's west side. Both victims sustained fatal gunshot wounds to the head and were pronounced dead at the scene.
The altercation reportedly began with an argument between a party attendee and a neighbor, escalating when the neighbor returned with family members. During the confrontation, 20-year-old Raul Trevino III allegedly opened fire, striking Medrano, Colin, and their 13-year-old daughter. Medrano, who was armed, returned fire, injuring Trevino and one of his relatives. The 13-year-old girl and the injured parties were transported to local hospitals with non-life-threatening injuries.
Authorities arrested Trevino, charging him with capital murder of multiple persons and aggravated assault with a deadly weapon. He was booked into the Bexar County Jail with bond set at $825,000.
Family members revealed that the initial dispute stemmed from an ongoing feud between two teenage girls, one being Medrano's daughter. The situation escalated when the other girl's family arrived at the party, leading to the fatal confrontation. Loved ones described Medrano as a devoted father and long-time H-E-B manager, and Colin as a loving aunt dedicated to her family.
Jennifer Colin was remembered as a responsible and hardworking individual who deeply cared for her family. She had just celebrated her 30th birthday the day before the incident. Her passing has left a significant void in the lives of those who knew her.
