It has been nearly three weeks since Lafayette resident Nathaniel Tallman went missing, and a $10,000 reward offered up by his family and friends has not yet helped elicit any information about his whereabouts, authorities say.

Tallman, 25, was last seen at about 6 p.m. Jan. 21 near the intersection of Empire Road and U.S. 287 in Lafayette, friends say.

He was driving his 2014 black Mitsubishi Lancer Rally with temporary tags.

Friends say Tallman was on his way to Longmont. He never arrived and has not been seen or heard from since.

Information about his whereabouts or that of his car also have not surfaced, despite family and friends announcing on Jan. 29 that they were offering a $10,000 reward for information useful to their search for the 2006 Monarch High School graduate.

“We're not doing very well,” Tallman's father Kevin Tallman said last week of the state of the family in the wake of his son's disappearance. “We're just trying to live every day waiting for good news.”

He urged people to share any information they may have and asked that people continue to look for his son.

“I would appreciate everyone's help in looking for my son and his car,” he said. “That $10,000, I'd be happy to give that to somebody if they could help us find our boy. It's a small price to pay.”

Lafayette police entered Tallman into the department's computer system as a missing person within days of his last being seen. Investigators have notified other state law enforcement agencies about Tallman's disappearance and have been following tips related to the case for weeks, according to the Lafayette Cmdr. Brain Rosipajla, but have no new information about where he or his car may be.

“The status of this case is still under investigation,” Rosipajla said. “We are asking the community if they saw anything to please call the Lafayette tip line. We are following up on all the tips we get.”

Nathaniel Tallman is described as white, with brown hair and hazel eyes, standing about 5-foot-10-inches tall. He was last seen wearing black sweatpants with a white stripe down the side and a white North Face jacket.

Friends and family told police they do not believe he intentionally ran away or took his own life.

Anyone with information about Nathaniel Tallman is urged to contact Lafayette police at 303-665-5571. Information also may be provided to his friend Zalyn Lee by emailing or by calling the Nate Tallman Reward Tip Line at 303-667-1639.
