LAS VEGAS -- Metro police are actively searching for the grandfather of a boy who was kidnapped from his home at gunpoint.

Clemens Fred Tinnemeyer was last seen in Las Vegas in May. Before he left the Valley, police said, Tinnemeyer stole millions of dollars in drug money from a Mexican drug cartel that he and members of his family were involved in.

Police said his family filed a missing persons report on Tinnemeyer shortly after his disappearance. He was last seen driving a white 2004 Dodge with Mississippi license plates KA6251.

Tinnemeyer is the grandfather of Cole Puffinburger, who was kidnapped from his home at gunpoint Tuesday by two Hispanic men disguised as police.

Puffinburger was abducted by members of the cartel Tinnemeyer was involved in to "send a message" to the grandfather, police said.

Puffinburger is 3 feet 11 inches tall and weighs approximately 48 pounds. He has blond hair, blue eyes, distinctly stained front teeth, an overbite and wears prescription, silver-rimmed glasses. He was last seen wearing a black, zip-up, hooded sweatshirt with white, black and blue stars on it; a black John Cena WWE wrestling shirt; dark jeans; a belt; white socks; and black Vans sneakers.

The men are described as having Hispanic accents. One man is described as in his early 30s, 5 feet 7 inches tall and weighing 150 pounds. He has black, shoulder-length, slicked-back hair. He was last seen wearing a white T-shirt and blue jeans, Rivera said.

Anyone with information is asked to call Metro police at 702-828-3111.
