DOYLESTOWN, Pa. (CBS/AP) Prosecutors are seeking the death penalty in the suburban Philadelphia trial of Omar Cash, accused of carjacking a couple, raping the woman and killing her boyfriend, in May 2008.

Police say Cash, who's 28, carjacked Edgar Rosas-Gutierrez outside a northeast Philadelphia nightclub. They say Cash forced the 32-year-old Gutierrez to drive while he raped his girlfriend, then killed the man in Bensalem, Pa., before driving the girlfriend to a New Jersey motel, where she escaped.

Cash denied the charges testifying Tuesday in Bucks County Court. He claimed that an acquaintance had arranged for the woman to meet him at the motel, and she fled after taking money. Prosecutors asked why he had never told police that story before, and Cash said they wouldn't listen to him. Cash's testimony is in stark contrast to that of the alleged rape victim.

Last Friday, the woman told the jury that Cash laughed and sang along with the radio moments after he murdered her boyfriend and left his body along the side of the highway. The 43-year-old woman said she believed that Omar Cash would also kill her.

Cash is also charged with another murder in Philadelphia.
