STOCKTON, Calif. — Crystal Rea has been seeking answers surrounding the circumstances of her daughter’s murder for years.

Shylee Martinez was at a house party on Nov. 7, 2015 when someone opened fire, according to the Stockton Police Department. Martinez, 21, was shot and killed.  

Martinez's death is one of hundreds of more than 500 cold cases in San Joaquin County.

While Rea continues to hope for answers, no new details have come to light in her daughter’s case in four years. 

A Grand Jury investigation brought the issue of unsolved killings to light earlier this year through a 27-page report. However, departments in the area are refocusing on the issue, which gives mothers like Rea hope.

“All I want is justice, you know,” Rea said. “At least a piece of mind... I hate having to worry about this day every year.”

On the fourth memorial of her daughter's death, Rea met with family and friends who lit candles, wrote messages on balloons, prayed, and sent paper lanterns in the air to remember the young woman.

“She always loved to come down and just walk around. She loved to be by the water,” Rea said.

Rea is calling for anyone with answers to come forward. Anyone with information can contact the Stockton Police Department or Crime Stoppers.
