[KHTS] – A convicted murderer from Acton who was charged with rape in June recently had a weapons charge added to four counts of rape this week.

Arthur Edward Lindsey, 73, was accused of possession of a firearm, which is not allowed by Lindsey because he is a convicted felon.

A judge determined there was enough evidence to add the charge to several that Lindsey is already facing.

Lindsey’s next court date will be Oct. 17, when he will be expected to file a plea for the weapons charge, and then have a pretrial hearing on the rape allegation.

Officials with the District Attorney’s Office said that the cases, which are being prosecuted by Deputy District Attorney Jon Hatami, will likely be consolidated and prosecuted together.

“We filed two counts (Friday) of rape of an unconscious person, one count of oral copulation of an unconscious person and one count of sexual penetration by a foreign object,” said Jane Robison, spokeswoman for the District Attorney’s Office.

Lindsey has a record of violent sex crimes.

“He’s a three-striker,” Hatami said, adding that he planned to seek a life sentence in the case.

Lindsey was convicted of a rape-murder in Indiana in 1968.

“He pleaded no contest to not being registered as a sex offender (on May 18, 2005),” Robison said. “He was sentenced to four years in state prison.”

Lindsey moved to Southern California in 1998, after he was released on parole for his murder sentence.

Lindsey’s most recent registered address is 10645 Soledad Canyon Road, Apartment A, in Acton, according to California’s Megan’s Law website.

Lindsey was deemed a “low-to-moderate risk,” according to a Feb. 1, 2011, scoring on the Megan’s Law website.

The case is being investigated by the Special Victims Bureau of the Los Angeles County Sheriff’s Department.
