Here's the latest from a 9:10 p.m. press conference from authorities about the shooting this afternoon; information is pulled together from the FBI, Broward Sheriff's Office and other news sources.
From FBI spokesman Tim Donovan:
It started at about 2:20 p.m., when a man stole a car at the intersection of 75th Street and 27th Avenue south of the Broward County line. He drove north, robbed a barber shop, and then stole an Infiniti that he used to escape onto the Florida Turnpike. He crashed the car, and when a Key Biscayne officer driving by stopped to investigate the crash, he shot her. An Immigration and Customs Enforcement agent who is believe to have stopped for the same reason was also shot. Then the suspect killed himself.
From Key Biscayne Police Chief Charles Press (earlier this evening):
The Key Biscayne officer's name is Nelia Real; she's been with the department for 16 years and arrived at the hospital awake, shot in the neck, and applying pressure to her own wound. She was transported there by an officer he believes was from the BSO. He said doctors were "cautiously optimistic" that the wounds were survivable, but changed his language a few times turing the conference. He said he didn't think she was going to die, but that she was still being stabilized.
The ICE officer was shot in the shoulder but it is non-life-threatening. The incident happened just south of exit 49 (Hollywood Boulevard).
From BSO spokesman Jim Leljedal:
A BSO deputy from Dania Beach was driving to the scene to assist, but crashed at I-95 and Sheridan Street and broke their leg. All three officers are at Broward Memorial Hospital.
From Florida Highway Patrol spokesman Sgt. Mark Wysocky:
Traffic will be diverted off the Turnpike until around 1 a.m.
