Steven Leslie O'Brien

Charlottetown, PEI — Steven O'Brien was last seen walking south on Queen Street in Charlottetown, Prince Edward Island, around 01:30 am on March 20, 1993. He was attending the Holland College Culinary Institute when he disappeared.

The Missing Children Society of Canada (MCSC), a national non-profit organization dedicated to the active search for abducted and missing children, began conducting a targeted poster campaign in Toronto and P.E.I. in 2010 on the 17th anniversary of O'Brien's disappearance because it was believed someone with information might come forward on the anniversary.

"Not one day goes by that we don't think of Steven," Janet O'Brien said of her son in a statement. "Our family is missing a piece of itself, and we miss him very much. We don't know where or why he disappeared, but what is most important to us, his parents, brother and sisters, is to know that he is alright."

The campaign used age-enhanced photos of O'Brien to show what he might look like at 35 years old. The MCSC offered a $10,000 reward for information leading to his location and continues to work with police on the case.
