ARLINGTON — They lined the sidewalk outside of Arlington's police department, holding signs and pictures of Evelia Valencia, hoping to bring attention to her death.
The 29-year-old mother of four was found strangled in her apartment a year ago Wednesday, and her case has grown cold.
On the anniversary of her death, friends and family held a rally at the city's police department to try and bring new clues.
"Someone out there knows something, I don't know why they won't speak up," Lico Reyes said.
The case has frustrated those closest to Valencia, as well as investigators. Arlington police have not made any arrests in the case, and say leads have grown cold.
Valencia was found in her apartment May 23, 2011, by her nine-year-old son. She had dropped her children off at school in the morning, and when they returned home she was dead in her bedroom.
Their three-month-old sister, who Valencia was home with, was discovered next to her on a bed unharmed.
Sources tell News 8, police still have multiple suspects in her murder, including former Arlington police officer Jose Mejia. He was fired by the department last May, just days before her death.
He was terminated by the city after Valencia filed multiple complaints against him, saying that the Arlington police officer was harassing her. Valencia's family said she feared Mejia, who told her father that he was threatening her.
"She was scared, the cop came to her door at three in the morning yelling," Augustine Villa said. "Then it was Friday, Saturday, Sunday and she was killed."
Arlington police say Mejia has lost his appeals to get his job back.
Prosecutors were considering filing charges against him for harassing the Arlington mother, but when she died, a spokesperson for the Tarrant County District Attorney's office said the potential charges could not longer be considered.
Jose Mejia could not be contacted Wednesday, and News 8 efforts to reach him in the past have not been returned.
The family hopes that the anniversary of her death will bring new clues, in a mystery that has grown colder and more frustrating by the day.
