PHILADELPHIA (CBS) – The death of Highway Patrolman Lorenzo struck hard at City Hall.

“The best way to put it, short and sweet: I loved Brian Lorenzo,” said Sgt. Michael Walton, the head of Mayor Nutter’s security detail, who knew and worked with Brian Lorenzo for many years.

“Good cops get to know good cops, and there is a bond when guys are out there doing the job, day in, day out.”

They met when Lorenzo was in the 25th District, but later worked together on the elite Highway Patrol. And Walton said Brian Lorenzo was among the best.

“Highway cops – it’s hard to put into words. They’re a special breed. It takes a special type of individual to become a highway cop.”

Lorenzo was 48 and leaves behind a wife and three children.
