Authorities say a woman siting on a couch in her Ohio home on the Fourth of July was killed when a bullet came through a front window and stuck her in the head.

It’s not clear who fired the shot or why. But Akron police say the bullet that hit 26-year-old Chelsey Jones may have come from more than 1,000 feet away and across Summit Lake.

They say the shot may have been fired by someone celebrating the holiday, noting two 9 mm bullet casings were found on a dock that can be seen from the house across the lake. Jones, the mother of two young daughters, had been watching television when she was shot.
