Missing Mark Lawrence Bosworth

Bosworth, approximate date 2011

Vital Statistics at Time of Disappearance

Missing Since: September 16, 2011 from Riddle, Oregon

Type: Endangered Missing

Date of Birth: April 19, 1957 Age at disappearance: 54 years old

Height and weight : 6'0, 180 pounds

Distinguishing Characteristics: White male. Gray hair, blue eyes. Bosworth may wear prescription Converse eyeglasses with black rims for reading. He is balding and may have a short gray beard. He has two small scars on the back of his head. Clothing/Jewelry Description: A gray hooded Cycle Oregon sweatshirt that says "Going Coastal," black shorts, dark-colored thermal leggings, a yellow Cycle Oregon baseball cap, a Petzl head lamp, two-tone brown Shimano bike shoes with the word "Shimano" on the outside of the heel and the letters "SPD" on the outside of the toe, a blue plastic Cycle Oregon wristband, and a black shoulder bag. Photos of the sweatshirt and hat, the shoes, the wristband, and Bosworth in those clothes are posted below this case summary.

Medical Conditions: Bosworth was diagnosed with non-Hodgkins lymphoma, a cancer of the blood, in 2007. He underwent chemotherapy and went into remission, but the cancer returned in his eye in 2009, and he had more chemotherapy treatments as well as radiation. Bosworth had a bone marrow transplant in April 2010 and went into remission afterwards. At the time of his disappearance, he had been complaining of severe headaches and had been confused and disoriented; his oncologist believes the lymphoma had possibly metastasized in the frontal lobe of his brain. If this scenario has in fact occurred and the cancer is left untreated, Bosworth will become increasingly confused and then die in a matter of weeks or months.

Details of disappearance and psychic work by Brian Ladd (login to view entire case )


Bosworth was last seen at a Cycle Oregon event in Riddle, Oregon on September 16, 2011. He had volunteered to run a booth on Main Street near Riddle High School that evening and he was last seen walking along a road between Riddle and Canyonville, Oregon sometime between 11:00 and 11:30 p.m., after leaving his booth. He said he was going to find his tent, but he never arrived there and has never been heard from again.
On the day of his disappearance, Bosworth had appeared exhausted and wasn't acting as he usually did: he was extremely quiet and didn't participate much in the event. He is unfamiliar with the Riddle area. He was carrying less than $100 in cash on him when he vanished, probably about $40, as well as an iPhone 4 with a dead battery and possibly a small black bag with straps. He left his bicycle, wallet, credit cards and identification behind.
