PHILADELPHIA — Gov. Ed Rendell on Sunday asked the Legislature to end parole for repeat violent offenders and said the state would expand its supervision of such offenders who have already been paroled.

The request came a day after Rendell said he received the criminal history of a man who he said had been paroled three times before allegedly killing two people in the Philadelphia suburbs last year.

He also cited the deaths of two Philadelphia police officers allegedly killed by parolees in 2008.

"These murders cry out for changes in how we sentence our violent repeat offenders who use deadly weapons," Rendell said. "This is a situation that simply has to change."

Under the governor's proposal, repeat violent offenders who use a deadly weapon in the commission of a crime would receive flat sentences without parole. Currently, sentences are given as a time span — for example, five to 10 years — and offenders are eligible for parole after serving the minimum.

Once offenders serve the flat sentence, Rendell has proposed a five-year supervision period by the parole board. Violators could be sent back to prison.

The proposal should garner a lot of support from lawmakers when the legislative session begins Tuesday, said Bob Caton, spokesman for House Speaker nominee Rep. Keith McCall, D-Carbon.

"I cannot imagine anybody having a problem with keeping repeat violent felons behind bars for as long as possible," Caton said Sunday.

Sherry Tate, spokeswoman for the Pennsylvania Board of Probation and Parole, said board members have been refining their criteria for release and are looking more closely at factors of violence and guns in making their decisions.
