An Arizona man was mauled to death by a bear in an unprovoked, random attack on his property Friday morning, authorities said.
Tucson resident Steven Jackson, 66, was found dead next to the black bear in Groom Creek, the Yavapai County Sheriff's Office
said in a statement. Jackson was outside drinking coffee on his property where he was building a home, when the animal began attacking him shortly before 8 a.m. local time.
"It appears that a male black bear attacked Mr. Jackson, taking him unaware, and dragged him approximately 75 feet down an embankment," the sheriff's office described.
After hearing Jackson's screams, neighbors attempting to deter the bear by shouting and honking their car horns, but the animal did not relent.
