Trent Collier was 45 when he vanished from Tooele County, Utah. He was last seen on July 30, 2008, after dropping off his children at an address in Grantsville. His brother reported him missing on August 12, 2008, after family communication ceased. Deputies searched Collier’s home and reported no signs of foul play.

Investigators learned Collier had sold his motorcycle on July 22, 2008. In early August he purchased a Delta Airlines ticket from Salt Lake City and later bought a train ticket in Santa Cruz, California, suggesting he left the area voluntarily. On September 21, 2013, Customs and Border Patrol agents at JFK Airport identified him by fingerprints; he was reportedly using the name Richard Koller and had bought a ticket to Jamaica. The case remains an active missing person investigation.

Does anyone have information about Collier’s travels or the alias Richard Koller around 2008–2013?
