(KSL News) -- West Valley Police don't have any strong leads on a brutal stabbing of an elderly woman, and now they're offering a 10-thousand dollar reward for help.
Here's a composite sketch of the attacker.
A man wearing a ski mask attacked 61-year-old Jill Johnson while she was volunteering at her church's food pantry.
He demanded money, stabbed her four times, and then took off in her Cadillac. Police say he's between 5 foot 8 and 6 feet tall.
Chief Buzz Nielsen, West Valley City Police Dept.: "He's a bad person, and somebody knows where he is out there, and has information on this case."
Police offered a similar reward after a man severely beat 86-year-old Georgina Anderson. Her attacker kicked her in the chest 30 to 40 times.
Police say it's too early to tell if the same man is responsible for both attacks.
