When asked about Brogan Rafferty, Beasley said that she has known him since he was 8 years old, since they go to the same church. Beasley called Brogan a "really nice kid" and said he struggled a bit in school and with his parent's divorce.
"They were friends," Beasley said. "Richard tried to mentor him, get him into history."
Beasley said her son had been struggling financially to make ends meet, working as an unpaid chaplain, and had other problems. She said he had spent time in jail and desperately did not want to go back.
"I've lived long enough to know that you have to be prepared for anything," Beasley said. "I'm just praying they've got the wrong people."
Rafferty is being held at the Muskingum County Juvenile Detention Center, and Beasley is in custody at the Summit County Jail on a $1 million bond.
A judge has imposed a gag order so that no further information about the case could be released.
Craigslist, an online marketplace that hosts ads for a wide variety of sales and services, has been blamed for a number of crimes and deaths, including the 2009 murder of a New York masseuse allegedly killed by a Boston medical student she met through the website, and the 2010 murder of a Tacoma, Wash., man in a home robbery committed by people pretending to be interested in a diamond ring he'd advertised on Craigslist.
