RICHARDSON, TEXAS -- A suspected gunman who fatally shot a Richardson police officer and a civilian was taken into custody following a standoff at an apartment complex Wednesday night.

The standoff lasted several hours before the suspected shooter surrendered to authorities. He was rushed away in an ambulance. His condition remains unknown at this time.

The incident started at about 7 p.m. Officers were called to the scene on a report of a disturbance at the Breckinridge Point Apartments near E. Renner and North Star roads. When they arrived at the scene, the suspect fired shots, hitting one of the officers.

He was rushed to Medical City Plano, where he was pronounced dead hours later, police said. The officer's identity hasn't been released at this time.

The active-shooter situation continued as a growing police presence surrounded the apartment building. A Texas Department of Public Safety helicopter hovered over the scene. During a negotiation with police, the shooter, barricaded inside the complex, continued to fire shots.

After the standoff, officers recovered the body of a second victim at the scene.

Earlier, officers shutdown Renner Road and urged residents to shelter in place.

Law enforcement and officers are paying their respects to the fallen officer. Shortly after midnight, Fort Worth police officers arrived at the hospital. Texas Gov. Greg Abbott posted a message on Twitter.
