Prince George County officials are still searching for the killer of a Suffolk woman whose body was discovered in the truck of her car last summer.

The body of Rebekah I. Brown, a senior correctional officer at Sussex I State Prison who lived in the Holland community, was discovered on June 28 in the trunk of her car. Although Prince George authorities refused to confirm the information, a recent forensics report listed Brown’s cause of death as asphyxiation.

Detective Corp. Brian Kei, a spokesman for the Prince George County Police Department, said the case is progressing.

&uot;We are still working the case but we have nothing further to report at this time,&uot; Kei said. &uot;We are still following up leads and receiving occasional tips from the public.&uot;

Kei said authorities are still awaiting test results from the state division of forensic sciences.

Kei acknowledged that authorities have interviewed a former boyfriend that lived with Brown until 10 days before her death. The boyfriend is a former inmate from the prison where she worked.

&uot;He has not been ruled out,&uot; Kei said. He refused to release the boyfriend’s name.

&uot;Any speculations would be premature.&uot;

&uot;But I am confident we will find the killer,&uot; Kei said. &uot;These things just take time.&uot;
