Police said a man charged with killing a Connecticut college student threatened to kill the woman after she tried to break off their relationship shortly before she disappeared in April. Arrest and search warrant affidavits were released Monday in the murder case against Jermaine Richards, 30, of Bridgeport. He is charged with killing 20-year-old Eastern Connecticut State University sophomore Alyssiah Wiley. Wiley was last seen in Willimantic April 20, and her dismembered remains were found a month later in Bridgeport. Authorities said in the warrants that Richards told a friend he was going to get rid of Wiley after she tried to break up with him.
