WEST VALLEY CITY, Utah (ABC4) – West Valley City Police Department is once again seeking the public’s help in gathering information about a homicide case that has gone cold.

On Dec. 12, 2016, 20-year-old Javier Medina was in his aunt’s driveway on Bendixon Drive when two men drove up to him, got out of their car and shot him, killing him and injuring a woman.

Investigators have reportedly exhausted all leads and still have not been able to pull together the evidence needed to solve the case. Now, investigators are asking the public for information about the case.

“We just want them to pay for what they did,” said Rosie Carriolo, Medina’s mother. “And why did they do it? I don’t know. I need closure for that.”

Medina had just turned 20 years old and welcomed a baby boy into the world. The mother of his child, Ezme Coronado, witnessed the shooting, and she said she still gets flashbacks.

“Six years later, and it feels like it just happened yesterday,” Coronado said. “We had a lot of plans, and [they were] stolen from us.”

Coronado added that Medina dreamed of opening up his own auto shop, and he lit up every room he walked in.

Police do not have a motive, but they believe there are at least two suspects involved who drove a light-colored Cadillac.

Anyone with info is asked to please call West Valley City Police Department at 801-840-4000. Callers can remain anonymous.

At the time of the incident, ABC4 reported Medina’s aunt said she knows who killed her nephew and spoke to the police. According to Medina’s aunt, it was an argument between him, his girlfriend, and his girlfriend’s ex-boyfriend that led to the shooting.

Medina reportedly had a child together with the woman injured in the shooting, saying she “is devastated to know that the child will group up never knowing their father.”
