ROUND ROCK, Texas (KXAN) - Round Rock police are combing the area around a home Monday morning where an officer-involved shooting left two people dead less than 24 hours prior.
Jonathan Demarco, 20, allegedly shot and killed his 23-year-old ex-girlfriend, Sarai Valdez, in the frontyard of a home in the 1900 block of Nicole Circle on Sunday evening. Police shot Demarco dead shortly after when he pointed a gun at them.
Crime scene tape still blocked the entry to the cul-de-sac late Sunday night, and detectives continued to investigate Monday morning -- collecting evidence as city workers weeded the area and a police dog sniffed the trimmed area.
Investigators also employed metal detectors to help collect evidence neighboring the home.
Round Rock police say they are now investigating both the officer-involved shooting and the killing that happened.
It began around 5:20 p.m. when police said Demarco shot Valdez before then pointing his gun at officers, refusing to stand down after being ordered to put the gun down. Two police officers then shot and killed Demarco.
Investigators said neighbors called police after seeing the ordeal unfold. Round Rock police said Demarco did not live with Valdez at the time.
Investigators are working to figure out why Demarco showed up to the home.
Round Rock Police Chief Tim Ryle says there were several kids at the home when the shooting happened. Once Demarco arrived, the Valdez reportedly rushed the children inside -- where they were later found unharmed.
Meanwhile, the Round Rock police officers involved in the shooting are currently on administrative assignment, which is protocol for shooting-related incidents.
