"She was always real friendly, always come over to the fence to talk to me," said Doyle Stogner, a neighbor.
Stogner said Sisson welcomed him into the neighborhood about two years ago.
"She talked to me all the time and I'd go over there and do her yard work a lot," said Stogner.
Police arrested Clarence Cannon on charges he killed Sisson. Officers spent the morning looking for clues at this abandoned car wash nearby.
Neighbors told us that last week, Cannon took Sisson's lawn mower to cut the grass at a pawn shop and left the mower there. Sisson drove by the shop and recognized it.
"The pawn shop people brought her home and brought the lawn mower home to her," said Stogner."
We found clothes around at the car wash. Neighbors said that's where Cannon lived after his wife kicked him out.
"He's listed as homeless so I think they did obtain information that he lived in the area," said Sgt. Cassandra Davis, spokeswoman for the Little Rock Police Department.
Among the other questions still lingering: Where is Sisson's dog? Stogner says she rarely left home without it.
"I know that dog barks. If it's anything around, it would let you know," said Stogner.
