Samuel Flowers, 21, was arrested on suspicion of grand theft, petty theft and resisting arrest in Bal Harbour, Fla., the FBI told Berkeley police early Monday morning.
Flowers, an alleged gang member, was wanted in connection with the shooting death of 25-year-old Berkeley resident Charles Davis and a subsequent high-speed chase that ended in a crash that killed two bystanders, 27-year-old Brentwood resident Todd Perea and 41-year-old Berkeley resident Floyd Ross, police said.
The incident began shortly after 6:30 p.m. when a Berkeley police officer heard gunshots in the area of Allston Way and 10th Street in west Berkeley.
Officers responded and found Davis on Allston Way west of San Pablo Avenue. He had been shot multiple times and was pronounced dead at the scene, police said.
As they were arriving, officers saw a Cadillac occupied by four men speeding away from the area and chased it into Oakland. The chase ended when the Cadillac crashed into a Mazda and a pedestrian at Aileen Street and Martin Luther King Jr. Way, killing both the driver, Perea, and the pedestrian, Ross.
After the crash, police arrested 24-year-old Oakland resident Anthony Price and 22-year-old San Leandro resident Stephon Anthony, but Flowers and a fourth suspect, 27-year-old Rafael Campbell, managed to flee the area on foot.
Campbell remains at large and should be considered armed and dangerous, police said.
The Alameda County District Attorney's Office charged Anthony, who authorities believe was driving the Cadillac, and Price last week with three counts each of murder as well as the special circumstance of committing multiple murders, which could make them eligible for the death penalty.
They were also charged with weapon and gang enhancements.
Flowers is being held at the Turner Guilford Knight Correctional Center in Miami awaiting extradition, police said.
The city of Berkeley and Bay Area Crime Stoppers offered a $47,000 reward for information leading to the arrest and conviction of the suspects.
