A truck driver on trial in the deaths of two women pleaded guilty Monday to killing four women and taking part in the slaying of another.

All the women were prostitutes whose bodies were found in the Toledo area between 2000 and 2005, prosecutors said.

Dellmus Colvin, 47, pleaded guilty to aggravated murder and complicity to commit murder. In exchange, prosecutors agreed not to seek the death penalty.

Lucas County Common Pleas Judge Thomas Osowik sentenced Colvin to two consecutive life sentences with no chance for parole.

Colvin admitted to the killings Sunday night during a meeting with police and prosecutors, Assistant Prosecutor Tim Braun said.

"He finally came clean about a number of other killings he had been involved with," Braun said.
