Vowell has a warrant for his arrest on two counts of first degree murder for slaying 26-year-old Chance Black and 25-year-old Zachery Grooms on Monday, January 25.

Crews have been searching for Vowell now for two days, but due to recent rainfall in the area, which caused the level of Reelfoot Lake to rise, he’s not thought to be out on the water anymore, and the search was called off temporarily until the lake level recedes. 

It’s surmised that Vowell may have died from exposure out on the lake, or was helped by someone out of the water. Vowell has no prior criminal record in the state, and a motive for the shootings (aside from the eyewitness’ description of an altercation) remains unknown.
