FILE - In this Dec. 1, 2011 file photo, Richard Beasley, 52, appears in Summit County Common Pleas Court in Akron, Ohio, on drug charges. Confusion over rules governing prisoner transfers and lack of communication helps explain why Beasley, now suspected in a deadly Craigslist robbery scheme, was mistakenly released from Ohio custody twice, according to a state prisons report.

AKRON, Ohio — A self-styled chaplain suspected in a deadly scheme to rob people who replied to a Craigslist job ad has been charged with multiple counts of aggravated murder, kidnapping and robbery and could face the death penalty if convicted, according to an indictment announced Friday.

The charges against Richard Beasley accuse him of killing three men and wounding a fourth in August, October and November.

Beasley, 52, of Akron, who has been jailed in Akron on unrelated prostitution and drug charges, has denied involvement in the Craigslist slayings. He was arrested in November after authorities linked him to the alleged plot.

Prosecutors would not speculate on a motive but Attorney General Mike DeWine, who joined in announcing the charges, said investigators are looking at "serial killings."

"Are there more bodies? We frankly do not know," DeWine said.

An acquaintance of Beasley, 16-year-old Brogan Rafferty, of nearby of Stow, could face similar charges after being transferred to adult court late last year. His case is pending in Noble County where two of the slayings happened.

Authorities say the scheme targeted older and single out-of-work men with backgrounds that made it unlikely their disappearances would be noted right away.

The first victim, Ralph Geiger, 55, of Akron, was killed Aug. 9, the day after he left a homeless shelter saying he was taking a farm job. His body wasn't found until Nov. 25.

The plot's second victim, David Pauley, 51, of Norfolk, Va., came to Ohio in mid-October after answering the Craigslist ad. A friend has said Pauley was desperate for work and eager to return to Ohio.

Police say he was killed Oct. 23, and his body was found Nov. 15. Family members had contacted police concerned they hadn't heard from him.

The third victim, Timothy Kern, 47, of Massillon, whose body was buried near an Akron shopping mall, answered the ad and was last seen Nov. 13, authorities said. His body was also found Nov. 25. Kern told his family he was taking the job to help support his three sons.

A surviving victim, Scott Davis, 48, of South Carolina, also answered the ad and was shot Nov. 6 before escaping, police say.

Beasley was a Texas parolee when he returned to Ohio in 2004 after serving several years in prison on a burglary conviction. He was released from an Akron jail July 12 after a judge mistakenly allowed him to post bond on a drug-trafficking charge.

He was arrested two days later following a traffic stop but again mistakenly released. An investigation by Ohio's prisons system found that Beasley should not have been released on bond but said confusion over interstate prisoner-transfer rules and "ambiguity" in messages from Texas to Akron jail officials contributed to the error.

In a four-page handwritten letter to the Akron Beacon Journal, Beasley has said he has been miscast as a con man when he really helped feed, house and counsel scores of needy families, alcoholics, drug addicts, the mentally ill and crime suspects for years.

"To call me a con man when I sacrificed for others is wrong," wrote Beasley, who didn't mention the Craigslist investigation or Rafferty. "To turn their back on me is not following Christ's example. I gave three full years of my life to that ministry and what I got out of it was the satisfaction of doing the right thing. There was no 'con' to it."
