A career criminal who disarmed an officer and used the gun to fatally shoot the policeman and another officer admitted killing the men and begged not to be killed after he was captured, officials said.

Charles Harry Street, 34, of Boynton Beach, was arrested less than an hour after Monday's early morning shooting when he threw down one of the slain officer's service revolver, police said."I killed two cops," he told Broward County Deputy Gregory Mentzer. "Lord, don't kill me for it."

Street, whose criminal record is more than 20 pages long and dates to 1972, was charged Tuesday with two counts of first-degree murder and other charges in Dade County Circuit Court. He was ordered held without bond by Judge Jack Coe.

Street's most recent conviction was for attempted murder in West Palm Beach in 1980. He was released from prison 10 days before Monday's shootings.

Metro-Dade officer Richard Boles, 41, a four-year veteran with a wife and two children, died at Jackson Memorial Hospital shortly after the shooting north of Miami. Officer David Strzalkowski, 34, a six-year veteran with a pregnant wife and young son, also was killed.
