Man rigged door to electrocute his wife' in Tennessee

A Florida man is accused of rigging the front door of a home in an attempt to electrocute his estranged pregnant wife.

In a Facebook post Friday, Flagler County Sheriff Rick Staley called the case one of the "most bizarre domestic violence cases" he's seen.

Officials said 32-year-old Michael Scott Wilson was arrested on Thursday in Knoxville, Tennessee, and charged with attempted aggravated battery on a pregnant woman and grand theft of a firearm.

He's being held on a $US150,000 bond and will be extradited to Florida.

It's unclear if he has a lawyer.

The woman's father called deputies after Wilson made suspicious statements about keeping children away from the door.

Deputies found the front door barricaded, with burn marks.

When a deputy kicked the door, a large spark was observed.

Wilson had changed his Facebook relationship status to 'widowed'.He was involuntarily hospitalised for mental evaluation in late November.

Deputies also found pictures of a sonogram on the kitchen table, love letters in the bedroom and the wife's recently-installed smart cameras dumped in the toilet.
