Key West hotel worker Geovani Perez, 29, died overnight from stab wounds sustained in a Thursday night fight with co-worker Francisco Leon Marquez, 36, police say.

Police are searching for Marquez, who they say was injured during the fight at the Ibis Bay Resort on North Roosevelt Boulevard.

Marquez, described as Cuban, is about 5 foot 6 inches tall with a short "buzz haircut," police said. Police received a call from the hotel around midnight; the two men were engaged in some sort of altercation when Marquez allegedly pulled a knife. Perez was airlifted to a Miami hospital where he was declared dead. Police are asking anyone with knowledge of Marquez's whereabouts to Key West detectives at 809-1015. To remain anonymous, call Crime Stoppers of the Florida Keys at (800) 346-TIPS.

This is the third apparent homicide in Key West since Sept. 2, when Carl Eric Johanson, 66, was found dead in his apartment at the Henry Haskins Senior Citizen Plaza on Kennedy Drive, bound and with his throat slashed. Tod Geofrey Helfrich, 46, is the prime suspect in the Johanson investigation, although he has not been charged as prosecutors await forensic analysis by the Florida Department of Law Enforcement. Helfrich is being held at the Monroe County Detention Center on charges of probation violation and grand theft after he was caught in Orlando with Johanson's car, cell phone and credit card.

Peter Erik Hedvall, 26, is charged with first-degree murder in the Oct. 28 killing of Venezuelan native Jonathon Alvarado, found dead under a truck on Grinnell Street. Police say his head was smashed with a rock.
