ATCHISON (AP) — Police in northeast Kansas are asking the public’s help in finding a 70-year-old man missing since Dec. 31.

Atchison Police Chief Mike Wilson said on Wednesday his department has received several leads since a Silver Alert for Garry Clyde Sandy was issued Jan. 10.

Wilson said there was a possible sighting of Sandy’s gold-colored 2005 Dodge Ram 1500 pickup early Saturday in Newton, about 160 miles southwest of Atchison. Investigators are following that lead, among others, while also watching for any financial transactions.

Sandy is described as 5 feet 8 inches tall and weighing 200 pounds, with thinning brown hair. Police said he always wears a Kansas City Chiefs ball cap and jacket and is known to frequent casinos.

He has a heart condition and is diabetic.
