Dallas homicide detectives are hoping you can give them new clues to a nine-month-old murder of a mother killed in her home.

Rosa Elia Paz-Perez was murdered last September. Her 3-year-old toddler was in the home with her when she was killed.

Police believe a robbery is at the root of Paz-Perez' murder. The only clue they have is a few seconds of video of a car they are sure carried her killer.

Dallas Homicide Det. Cayce Shelton has been investigating the case since Paz-Perez was killed in her home in the 9300 block of Sedgemoor Drive on September 12. He believes video shows the black two-door Honda Civic that the killer drove.

“The suspect entered through the front door and left through the front door. All the other doors were locked,” Shelton said. “It was ruled blunt force injuries. She was basically bludgeoned.”

That day, Paz-Perez wasn’t supposed to be home at 9 a.m. She was supposed to be at a Zumba class.

“She had a small child. Had a 2-year-old, and she didn’t make it to Zumba,” Shelton said. “It was a daily deal.”

Every room in the house was ransacked because they were looking for money. Several thousand dollars were stolen.

Paz-Perez’s sister doesn’t want to be identified because they don’t know who the killer is.

Someone has to know. Someone can’t just commit this type of crime and keep it to themselves,” she said. “I just don’t understand. It’s traumatizing for everybody”

The two-door black Honda Civic is the only clue police have

“With the field of vision for the camera and the speed of the car, you really can’t make out the driver or any occupants,” the detective said. “We want the person that knows something about it, that knows the person that did it or knows the person that was driving the car. Or even just give me the car. I’ll do the legwork. Give me the car.”

Anyone with information on the case is urged to contact Crime Stoppers at (214) 373-8477.
