UPDATE: Neighbors on alert after Border Patrol agent shoots, kills suspect in Green Valley

TUCSON, AZ (Tucson News Now) - A chase that started with a suspicious vehicle on Interstate 19 Friday afternoon ended with a deadly shooting near a golf course in Green Valley.

Customs and Border Protection confirmed that an agent shot and killed a suspect while in pursuit.

According to CPB, agents tried to stop a suspicious car on I-19, near Green Valley. The driver refused to stop, and instead sped away. The chase traveled off the interstate and onto Abrego Drive, near Torres Blancas Golf Course.

Eventually, the suspect got out of the vehicle, and tried to run away. That's when an agent fired his service weapon, according to CBP.

Lowell Gerdes and his wife, who live on the golf course, heard the gunshots Friday afternoon. Gerdes said he wasn't sure what it was exactly, but he had an idea because of the recent travel warning issued by the U.S. Consulate for Nogales, Sonora.

"As soon as I made that connection I thought okay this is something," he said. "And it was a first for us."

Gerdes said he notices agents on patrol most days, but never in force like he saw Friday. Though not worried about another incident, Gerdes said he would make sure the family's security system was online.

After the shooting, CBP confirmed that agents found bundles of marijuana in the suspect's car. Fawn Brown, who showed up Friday night to protest the crime scene investigation said the evidence of drugs does not justify deadly force by Border Patrol agents.

"There's just no accountability for their actions," she said. "They're way down here in the middle of nowhere and they feel they can do anything they want. It's got to stop."

The agent involved in the shooting will be on paid leave for three days, according to agency protocol. No names have been released at the time of this report.

The Pima County Sheriff's Department is investigating the incident.
