Authorities in South Florida searched Tuesday for a suspect believed responsible for three armed carjackings and shooting two people, one fatally.

Fort Lauderdale police spokeswoman Deanna Greenlaw said the victims, a man and a woman, were shot multiple times outside an insurance office in Hallandale Beach. The FBI later said the man had died. Their identities were not immediately released.

Greenlaw said after the shooting, the suspect then drove a stolen car north on Interstate 95, crashing near downtown Fort Lauderdale and got away on foot. Some schools were locked down and traffic snarled on the busy interstate while authorities searched the area.

The FBI's Violent Crime Task Force was called in to assist.

The crime spree began shortly before 8 a.m. in Sunrise, where a woman and her son were ordered by the carjacker to drive to I-95, where they were released unharmed.

Police say the suspect then drove that car south to Dania Beach and committed a second carjacking, followed by the shooting and third carjacking.

The woman, who was in surgery at a local hospital, was believed by police to be the suspect's ex-girlfriend.
