AKRON, Ohio — A remorseful teenager was sentenced Friday to life in prison with no chance for parole for his role in a deadly plot to lure men desperate for work with phony Craigslist job offers.

‘‘I thought it was something horrible,’’ Brogan Rafferty, 17, told Judge Lynne Callahan before he was sentenced.

If his life has been hell since the killings last year, ‘‘They must be living in it,’’ said Rafferty, gesturing with cuffed hands at victims’ relatives who crowded the court.

Rafferty told the judge, who will preside at the January trial of alleged triggerman Richard Beasley, 53, that his mentor is evil and deceitful.

Rafferty was convicted of aggravated murder and attempted murder in the deaths of three men and wounding of a fourth.
