Several agencies have searched for Kilgore, 33, since deputies found four people shot on his family's rural Middleburg property before dawn on Monday.
Kilgore's younger brother, Raymond, and his friend, James Coody, were killed, and Kilgore's parents were both seriously injured.
A VyStar account has been set up for Raymond Kilgore's family to help with funeral expenses. The account listed under Norma Griffin is No. 702842810. A VyStar account has also been set up to help Coody's family with funeral expenses. The account listed under James Allen Coody Jr. is No. 70284033.
Channel 4 was told a man matching Kilgore's description and armed with a shotgun and knife entered a convenience store near the Clay-Duval county border just before 9 p.m. Tuesday. A witness said the gunman ordered people in the store to "get in the bathroom or you are going to die," put a gun to a clerk's head, grabbed cash, cigarettes and candy, then took off.
"The fact that he's emerged out of the woods and conducted an armed robbery at least let us know he's still in the area," Beseler said.
The robber was driving a blue Chevy Trailblazer, possibly the same vehicle investigators believe Kilgore drove away from Monday's homicide scene. That SUV was found abandoned early Wednesday two miles from the store.
Beseler praised the level of cooperation between the agencies, including the U.S. Marshals Service and the Florida Game and Florida Fish and Wildlife Conservation Commission. He said even St. Johns County had sent its helicopter to assist in the search and Alachua County has offered to help with resources.
"We'll be in this community until we exhaust our search or capture the suspect," Mackesy said.
