MARTIN COUNTY — An apparent domestic donnybrook involving deer antlers and an eye-gouging grandmother left a 37-year-old man behind bars, an affidavit states.

Jacob Ashworth, of the 6400 block of Southwest Gator Trail in Palm City, was jailed on a battery charge after the Dec. 22 flap.

Martin County sheriff’s deputies spoke to Ashworth’s uncle, who said Ashworth “kept coming after him,” the affidavit states.

The uncle said he grabbed deer antlers to defend himself.

Ashworth told deputies he argued with his uncle, saying his uncle was making noise and disturbing him. Ashworth said his uncle got a deer antler and knife and threatened him.

Antlers are the branched, bony growths protruding from the head of male deer, known as bucks. Antlers grow in pairs, and are prized by deer hunters, who sometimes hire a taxidermist to preserve the head of a killed deer for display as a trophy-like object, often by hanging it in a den or living room.

Female deer, such as Faline in the popular animated movie "Bambi," lack antlers.

Meanwhile, Ashworth said “he didn’t know what to do.” He “attacked” his uncle, and got on top of him, the affidavit states.

“While they were struggling his grandma … came behind him and gouged his eye to break up the fight,” the affidavit states.
