Authorities are asking for the public's help in identifying a gunman who robbed, shot and killed a 69-year-old hiker in a "random" attack in Northern California.
Investigators have been following leads in connection with Friday's shooting death of Francis Patrick Gregory on a trail in Red Bluff, said Tehama County Sheriff's Lt. Yvette Borden.
The random attack, she said, is rare for the area.
Gregory, of Massachusetts, and a friend were walking on the Iron Canyon Trail off State Route 36-E about 10 a.m. when the gunman confronted them and demanded money and their personal belongings, the Sheriff's Department said in a statement.
After robbing Gregory and his friend, 76, of Manton, the gunman shot and left them in a remote area 100 yards from the trail head.
Three hours later, another hiker found the pair and notified authorities.
Gregory died at the scene. His friend, whose identity has not been released, was listed in stable but critical condition Monday after being taken to a hospital.
The Tehama County Secret Witness program, a nonprofit group, has offered a $1,500 reward for the arrest and conviction of the gunman.
Gregory was described as prominent civic leader in Massachusetts who owned a computer store in Martha's Vineyard, the Associated Press reported.
The gunman was described as white, about 6 feet tall with a thin build and short black hair, a black mustache and beard. He was wearing dark denim pants and a dark T-shirt with an unknown print on the front.
Anyone with details about the gunman is asked to call sheriff's Det. Jeff Garrett at (530) 529-7920, ext. 3032, or the sheriff’s dispatch at (530) 529-7900. To remain anonymous, call the Tehama County Secret Witness at (530) 529-1268.
