FORT LAUDERDALE, Fla. -- Deputy Paul Rein, a 20-year veteran of the Broward Sheriff's Office, is the latest casualty of the force. Rein was allegedly shot and killed Wednesday by prisoner Michael Mazza, according to BSO investigators.

The Broward Sheriff's Office has suffered losses and serious injuries in the force in the past decade, with four serious shootings of BSO deputies this summer.

On Aug. 10, Sgt. Chris Reyka was killed in the parking lot of a Walgreens on Powerline Road in Pompano Beach. Investigators said he was checking on a car with stolen plates when the passenger in the car ambushed him.

On Aug. 6, Maury Hernandez was shot in the head Monday while conducting a traffic stop in the 3700 block of Pembroke Road. He underwent emergency surgery at Memorial Regional Hospital and has since recovered, but is undergoing rehabilitation.

In June, Deputy Edwin Gomez was shot in the left shoulder and arm during a confrontation in a neighborhood known for drug sales. Gomez survived, but the suspect in his shooting, Raymond Lawson, was fatally wounded in the gunfire.

In November 2006, Deputy Brian Tephford was killed and his partner, Corey Carbocci, was wounded during a routine traffic stop in Tamarac.

In August 2004, Kenneth Wilk shot and killed Deputy Todd Fatta while he was trying to serve a search warrant at Wilk's house in Fort Lauderdale. A high-powered round from a Winchester hunting rifle penetrated Fatta's bulletproof vest and hit him in the heart.

The bullet passed through Fatta's body and then hit Sgt. Angelo Cedeno in the hand and shoulder. Cedeno lost a finger from the incident.

In April 2003, Deputy Philip Billings died from a gunshot wound while working a security detail at an automobile dealership.
