A Connecticut parole board that ruled this year that a convicted cop killer could go free has rescinded that decision following an outcry from the victim's family and prosecutors.

The inmate, Gary Castonguay, is serving 25 years to life in prison for the 1977 shooting of Plainville police Officer Robert Holcomb.

A panel of the Board of Pardons and Paroles voted Wednesday to reverse its earlier ruling without any discussion at a hearing at the MacDougall-Walker Correctional Institution in Suffield.

The hearing was scheduled after Holcomb's family and prosecutors said they were unaware of the meeting in January when board members voted to release him. Holcomb's relatives and prosecutors say the earlier decision was made with inadequate information about Castonguay's violent background.

Several dozen police officers attended the hearing.
