According to at least two reports.

The first in the South Florida Sun-Sentinel:

… Authorities have charged [James Patrick] Wonder with first degree murder.

Segarra said Wonder was a patient at the dialysis center.

The arrest ends a hunt that included more than 500 police officers from local, state and federal agencies, traffic roadblocks and the use of military Blackhawk helicopters.

Pettit was shot and killed Tuesday morning in the parking lot of the post office.

Police said Pettit was with his daughter when he got into an argument with another driver.

Police on Wednesday said Pettit, an internal affairs agent with U.S. Customs and Border Protection, was on-duty at the time and had his gun in his car.

The shooting left Pettit’s family reeling and begging for justice.

“This man has destroyed my family and taken the love of my life,” said his wife, Ileana Pettit, at a news conference before the arrest.

Wonder has a concealed weapons permit, according to state records.

The second in the Miami Herald:

The man who police suspect killed a federal customs agent during a bizarre traffic dispute Tuesday was apprehended a day later in a Davie dialysis center after a massive manhunt, authorities said.

Police arrested James Wonder, 65, of Miramar, and charged him in connection with the shooting death of Donald J. Pettit, 52, of Pembroke Pines.

Pettit was gunned down — shot once in the head — in the parking lot of a post office at Pines Boulevard and Dykes Road as his 12-year-old daughter watched.

…

Wonder lives in Miramar with his wife of 30 years, Aurora.

Late Wednesday, she declined to speak with a reporter when reached by phone.

Her husband, who carries a concealed weapons permit, has no prior criminal history, according to public records.

Is this the kind of person the NRA’s Marion Hammer wants to take their guns to work in Florida, say, to Walt Disney World?
