Shooter was fixated on Zimmerman, report says

ORLANDO, Fla. -- A man charged with shooting at George Zimmerman last week had "a fixation" on the former neighborhood watch leader and recently had been admitted to a mental institution, according to a police report made public Tuesday.

The Lake Mary Police Department report said 36-year-old Matthew Apperson had shown signs of paranoia, anxiety and bipolar disorder.

Apperson's attorney, Michael LaFay, refused to comment on past hospitalizations of Apperson, but he questioned the qualifications of the police department to make psychological or psychiatric diagnoses.

"I'm unaware of any psychological or psychiatric degrees that are held by the officers at the Lake Mary Police Department," LaFay said Tuesday. "I'm going to take their diagnoses with a grain of salt."

Zimmerman told officers he was driving in the Orlando suburb of Lake Mary last week when Apperson got behind his truck and yelled, "You remember me, you fat mother f-----?" according to the report.

Apperson then yelled at Zimmerman, "You owe me your life. The only reason I didn't press charges on you is because I wanted to kill you myself," Zimmerman told detectives, according to the report.

Zimmerman and Apperson had a road-rage encounter in September, when Apperson alleged Zimmerman had threatened him. Apperson decided not to pursue charges, and police officers were unable to move forward without a car tag identified or witnesses.

Two days later, Apperson called police to report Zimmerman's truck was parked near the disability-benefits office where he worked. Zimmerman told police officers he had an appointment in the same office park, and no charges were filed.

In the most recent incident, Zimmerman told officers he laughed and called Apperson a clown, and Apperson fired a gun at his car a short time later, leaving a bullet hole in his passenger-side window. Zimmerman suffered minor injuries.

Apperson gave police officers a different account. He said Zimmerman had pointed a gun at him as they were driving, so he fired at him with his revolver. A detective at the scene said he overheard Apperson say, "I hope I got him this time," according to the police report.

Apperson was charged last Friday with aggravated assault with a deadly weapon, aggravated battery and firing a missile into an occupied conveyance. He was released over the weekend on $35,000 bond.

"Mr. Apperson behaved appropriately for anybody who has been threatened by Mr. Zimmerman," LaFay said."Mr. Zimmerman isn't known for his calm, collective reasoning."

Zimmerman was acquitted of any crime two years ago for fatality shooting unarmed teen Trayvon Martin. The case sparked protests and a national debate about race relations. The U.S. Justice Department later decided not to bring a civil rights case against Zimmerman.

Zimmerman has had several brushes with the law since his acquittal in 2013, including two assault complaints from two girlfriends. In both cases, the girlfriends refused to cooperate and charges were dropped. His estranged wife also accused him of smashing her iPad during an argument days after she filed divorce papers. No charges were filed because of lack of evidence.

Zimmerman recently moved away from Florida but had returned to the Orlando area for Mother's Day.
