LEXINGTON, Ky. (AP) -- Lexington police have filed a murder warrant in the disappearance of a chef at the University of Kentucky more than a month ago and have arrested a man on a charge of complicity to kidnapping.
Lexington police spokeswoman Sherelle Roberts wouldn't release the identity of the person charged, saying to do so could compromise the case.
She told the Lexington Herald-Leader the missing person case is being converted to a homicide investigation.
No one has heard from 32-year-old Alex Johnson since Dec. 20 when he ended a phone call with his girlfriend by saying he needed to answer the door at his home.
Police arrested 42-year-old Timothy Ballard on a charge of complicity to kidnapping and tampering with evidence.
Roberts said there could be additional charges in the case.
