AUBURN, Ala. (AP) — Authorities say additional human remains have been found in a creek where the leg of a missing man was discovered in east Alabama.

Officials told a news conference Friday that some of the remains were in trash bags, similar to the leg that was discovered by a construction worker in Cossey Branch Creek near the Macon and Lee County line.

Macon County Sheriff Andre Brunson says the remains are those of 32-year-old Kenneth McKency of Macon County. He was last seen near the Brownville area and was reported missing on Jan. 6.

Brunson says the missing person case is now a homicide investigation. Officers from Macon and Lee counties are trying to determine where McKency was killed, the cause of death and how the remains ended up along the creek.
