The Larimer County Sheriff's Office is asking for the public's help in finding a 93-year-old Berthoud man.

That's according to a post on the agency's website: According to the post, Grant Steffen did not return yesterday after a trip to the Loveland Library. He was driving a 2007 Light Blue Toyota Matrix.

He left the library around 1:10 p.m. and his vehicle was seen in Berthoud shortly before 1:30 p.m. Steffen has cognitive impairment and needs medication.

According to the post:

"Grant was wearing a blue LL Bean jacket, dark green wool shirt, jeans, and brown shoes. He’s a white male, 5’10 tall, 165 lbs, with gray hair and brown eyes, and has some memory/cognitive challenges. He does not have a cell phone and family is concerned that he may be lost. Please call 911 if seen."
