Updated at 11:40 p.m. with information about the Camaro that police want to locate.

A loss-prevention staffer at a CVS Pharmacy store shot and killed a person suspected of shoplifting after chasing down his getaway car Sunday afternoon in southeast Dallas, police say.

Police arrested 36-year-old Julio Ruvalcaba Monday on a murder charge.

Officers were dispatched to the shooting about 3 p.m. Sunday and found 31-year-old Christopher Geddes lying on the curb on the eastbound C.F. Hawn Freeway service road and Elam Road, police said.

He was taken to a hospital, where he died from his injuries.

Surveillance video showed Geddes shoplifting from the CVS on South Buckner Boulevard and running to a Toyota Camry in the parking lot, according to an arrest warrant affidavit.

Footage from several minutes later shows another person leaving the store and getting into a Chevy Camaro parked outside. CVS employees identified that person as Ruvalcaba, a loss-prevention staffer tasked with reducing shoplifting.

This is not the actual suspect vehicle, which police want to locate. (Dallas police)

Police are searching for his vehicle, which has not been recovered. It's a charcoal gray 2010 Chevrolet Camaro with license plate HKN-4449 and might have damage from a crash.

Witnesses reported seeing a Camaro chasing a Camry on the freeway. The Camry, in which Geddes was a passenger, crashed into a sign at the Elam Road exit ramp and spun out, flattening a tire, a witness told authorities.

Police say Ruvalcaba followed the Camry to the intersection, where Geddes got out of the Camry and walked toward the Camaro. Ruvalcaba then pulled a gun and shot Geddes in the upper torso before driving east on Elam Road, according to the affidavit.

Ruvalcaba was taken into custody and interviewed at Dallas police headquarters. He invoked his right to remain silent.

He remains in the Dallas County Jail.
