Twenty-nine-year-old Washingtonian Carlos Ricardo Hill was sentenced to 60 years in prison by a federal judge today following his conviction in the bludgeon slaying of a Washington prostitute along the Baltimore-Washington Parkway last year.

Hill is the last of three defendants, including his brother, Gilbert (Champ) Hill, 30, and Sherri Webb, 22, a one-time prostitute on Washington's 14th Street strip, to be sentenced in the widely publicized slaying.

All three were originally charged with kidnaping and second degree murder in the death of Pamela Mae Shipman, 24, whose battered and partially clothed body was discovered by U.S. Park Police in a secluded wooded area just off the Baltimore-Washington Parkway near Powder Mill Road in February 1982.

Webb pleaded guilty earlier this year to slaying Shipman with a 3 1/2-foot-long tire jack. She received a 25-year prison sentence and became a principal witness against the Hill brothers.

At separate trials for the brothers, Webb, an acknowledged $200-a-day heroin addict who told the court she earned up to $6,000 a week "turning tricks" at a Washington massage parlor, said the slaying stemmed from a dispute she and Shipman had over a mutual male friend.

She said Shipman set Webb's apartment on fire. In retaliation, she enlisted her current boyfriend, Champ Hill, and his brother, Carlos, to grab Shipman off the street and drive Shipman from downtown Washington to the Washington-Baltimore Parkway in suburban Maryland.

There, they stopped and dragged Shipman into a clump of woods where Webb said she bludgeoned the woman with the tire jack.

Champ Hill was convicted last March of aiding and abetting the slaying and received a 35-year sentence from U.S. District Judge James R. Miller. Carlos Hill was convicted July 8 of kidnaping and second degree murder.
