A man who called 911 to report a Florida shooting Monday said the gunman relayed that he “had to shoot at” George Zimmerman.

“A guy right here said he just had to shoot at someone through his window, so he wants the police to come,” the caller told a 911 dispatcher. The man later added that the motorist “said it was George Zimmerman.”

As authorities released the 911 audio Tuesday, a Lake Mary Police Department spokeswoman said was just the first half of the the call. “The rest has ‘pertinent information’ to the ongoing investigation,” the Orlando Sentinel reported.

Zimmerman, who was acquitted in the shooting death of unarmed Florida teenager Trayvon Martin in 2013, suffered minor injuries during the shooting Monday afternoon, in Lake Mary, Fla., police spokeswoman Bianca Gillett said Monday.

Zimmerman did not fire a weapon during the confrontation with Matthew Apperson, a man who last year accused Zimmerman of threatening to kill him.

“At this time, the investigation has proven that George Zimmerman was not the shooter,” Gillett said at a news conference Monday. “He was transported to a local hospital for minor injuries and has since been released.”

Gillett said Zimmerman flagged down a police officer shortly before 1 p.m. and “reported he was just involved in a shooting.” At the same time, someone placed a 911 call on behalf of Matthew Apperson, who said he was involved in a shooting with Zimmerman.

On Tuesday, investigators said they found two handguns in Apperson’s car. Police also said they “recovered” Zimmerman’s Glock handgun but hadn’t yet finished searching his car.

No arrests have been made, Gillett said, adding that police do not know why or how the altercation began.

Apperson and Zimmerman have crossed paths before. In September 2014, Apperson, 35, told Lake Mary police that Zimmerman threatened to kill him and said “do you know who I am?” during a road rage incident. Apperson declined to press charges.

Aside from that September run-in, Lake Mary police do not have additional reports of altercations involving the two men, Gillett said.

The Monday shooting took place near Trailhead Park on Lake Mary Boulevard, a busy road. Police Chief Steve Bracknell told the Orlando Sentinel that Zimmerman suffered injuries to his face.

Zimmerman’s attorney, Don West, told the Orlando NBC affiliate WESH that a bullet missed Zimmerman’s head. West said glass from the car windshield sprayed Zimmerman, who was visiting from out of town for Mother’s Day.

“George was driving down the road on Lake Mary Boulevard. This guy was sort of following him and flashing lights and such,” West told WESH. Zimmerman “decided to get away from him, decided to make a U-turn. And this guy made a U-turn right behind him and then pulled up alongside him and shot at him.”

Apperson’s attorney, Mark NeJame, said his client acted in self-defense but declined to offer specific details to WESH. “Why do you call the police if you’re the aggressor?” he said.

After his 2013 acquittal on charges of second-degree murder, Zimmerman was arrested after allegedly pointing a shotgun at his then-girlfriend during a fight. A month later, the girlfriend said she wouldn’t cooperate with the investigation, and prosecutors dropped the case.

Lake Mary police arrested Zimmerman earlier this year on suspicion of aggravated assault and domestic violence with a weapon involving a different woman, but those charges were later dropped.
