Brian Lancaster, a contestant on Season 7 of MTV’s reality series Road Rules, has died.

Lancaster died Thursday, March 29, in Phoenixville, Pennsylvania, according to an obituary posted on the Dellavechia, Reilly, Smith & Boyd Funeral Home website. The cause of death is under investigation. He was 43.

Lancaster was 23 when he competed on the seventh season of Road Rules in 1999. He competed on 13 different missions over the course of 15 episodes that were shot in Mexico, Costa Rica and the U.S.

The reality show debuted on MTV on July 19, 1995 and ran for 14 seasons, ending on May 9, 2007. The series followed five to six strangers, between the ages of 18 and 24, stripped of their money and restricted to a life in an RV, traveling from location to location. The strangers were guided by a set of clues and missions to complete at each location. It was nominated for an Emmy Award in 2001.

In the online obituary, Lancaster was praised as a “jack of many trades, including advertising account manager, telecommunications project manager, special education teacher, bartender, and reality TV star.”
