STUART, Fla. - The ex-husband of a Tennessee woman who disappeared nearly three years ago has been charged with trying to kill his girlfriend in Florida, reports CBS affiliate WTVF.
The attempted murder charge filed against Tyler Mook, 34, on Saturday stems from an October incident in which witnesses said Mook tried to drown his girlfriend following a fight aboard a boat in Florida, according to the station.
Mook was initially charged with domestic battery in the incident but the charges were upgraded over the weekend, the Martin County, Fla. Sheriff's Office says.
Mook is also named a person of interest in the 2011 disappearance of his ex-wife Shelley, with whom he had a young daughter.
Shelley Mook, a school teacher in Shelbyville, Tenn., disappeared after dropping their daughter off at Tyler Mook's home. Her car was later found burned in Murfreesboro, Tenn., near where the couple once lived. Her body has not been found.
Tyler Mook has never been charged in that case.
