James Allen Selby, 38, who was dubbed the "Bankers Hill Rapist" by San Diego police three years ago, killed himself Monday.

Selby was found hanging from the window of his jail cell just a few hours before he was scheduled to be sentenced to life in prison in Tucson for raping five women and a teenage girl there in 2001 and 2002. He used a bedsheet to hang himself.

Selby had been connected by a national DNA databank to the rapes and assaults of 14 girls and women in San Diego; Tucson; Colorado Springs, Colo.; Sparks, Nev.; and Norman, Okla. comma between September 1999 and May 2002.

San Diego prosecutors were planning to extradite him after the Arizona sentencing to face charges that he raped four women between July and September of 2001 in Bankers Hill, North Park and Park West.

Selby was accused of entering his San Diego victims' apartments through windows, covering their faces with a towel and assaulting them, according to court records.

Four days after the last San Diego attack, Selby attacked his first victim in Tucson.

Authorities believe Selby was a drifter who came to San Diego in 2001. At the time of his death, he was serving a sentence of 20 years to life for a Colorado rape conviction and faced multiple life sentences in Tucson.

A convicted serial rapist who faced a life sentenced, was found hanged in his jail cell hours before his scheduled court appearance.
