WINNIPEG -- RCMP say human remains found in a Manitoba hay field more than two decades ago have been identified as those of a man who disappeared in 1989.

Patrick Lawrence Rosner of Winnipeg was 20 when he was last seen leaving work at Bristol Aerospace the afternoon of June 23, 1989.

A farmer found a human skull in his hay field near Faulkner, Man., a year later and other human remains were located after a search.

Based on forensics of the day, it was believed that the remains belonged to a woman between 25 and 40 years old.

In 2011, the RCMP's historical case unit reviewed the file and DNA analysis confirmed that the remains were actually that of a male.

Police say DNA from family members was then obtained and Rosner's identity was confirmed last month.

The death is being treated as suspicious and the historical case unit continues to investigate.

RCMP are asking anyone who many have information about Rosner's death to contact police.

Faulkner is located about 200 kilometres northwest of Winnipeg.
