The former reality star was reportedly found dead at his home in Pennsylvania last week.

Brian Lancaster, who was a contestant on season seven of MTV's Road Rules in 1999, has died at 43.

The Chester County Coroner’s Office confirms to ET that the former reality star died on Thursday, March 29. According to authorities, his death is currently under investigation.

The DellaVecchia, Reilly, Smith & Boyd Funeral Home in West Chester, Pennsylvania, shared an obituary for Lancaster on its website, and hailed him as a "jack of many trades, including advertising account manager, telecommunications project manager, special education teacher, bartender, and reality TV star."

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

According to the obituary, a private service was held in memory of Lancaster on Wednesday for his friends and family.

Lancaster is survived by his fiancee, Sarah J. Bell, his parents, Dennis and Carol Lancaster, and "scores of other family [members as well as] old and new friends."

The obituary also notes that in lieu of flowers, memorial contributions in Lancaster's name may be made to the Brandywine Valley SPCA, a no-kill shelter in Chester and Delaware County, where Lancaster adopted his faithful companion, Reagan.
