Police say George Zimmerman helped rescue a family trapped in an overturned vehicle off a Florida highway last week, Zimmerman's first known public sighting since his acquittal in the shooting death of Trayvon Martin.

The incident occurred on July 17 in Sanford, Fla., near the intersection of Interstate 4 and State Road 46, officials confirmed to NBC News. The rescue was first reported by ABC News.

Zimmerman and another man were assisting a family of four when officers with the Seminole County Sheriff's Office arrived on the scene of the accident. A blue Ford Explorer had traveled off the road and rolled over, according to officials.  

Zimmerman and the other man were helping the two children and their parents get out of the overturned vehicle, the Seminole County Sheriff’s Office said. The former neighborhood watch volunteer left the scene after making contact with police and did not witness the crash.

There were no injuries to any of the vehicle’s occupants, according to police.

A Seminole County jury found Zimmerman not guilty July 13 in the death of 17-year-old Martin. Zimmerman said he shot Martin in self-defense on Feb. 26, 2012. 

Since then, Zimmerman’s family has said the 29-year-old was in hiding and had received death threats. Zimmerman’s parents said in an interview that they don’t even know where their son is hiding.

The verdict has prompted rallies and protests. Protests in Los Angeles and Oakland, Calif., turned violent as demonstrators called for an overhaul of the justice system and repeal of Florida’s “Stand Your Ground” self-defense law.
