Provincial police are asking relatives of two Stratford men who vanished nearly 60 years ago to provide DNA samples.
Huron OPP made the appeal on Wednesday in an effort to determine what happened to 29-year-old Neil Wormsbecker and 30-year-old Hank Englebertus Halff.
The men left from the Port of Goderich on a fishing trip in Lake Huron on October 22, 1967 and were never heard from again, police said.
Investigators are now calling on any living relatives of the pair to give samples of their DNA, which will then be compared against all samples of found human remains in the police database.
Police, along with the Ontario Center for Missing Persons and Unidentified Remains and the National Missing Persons DNA Program, are working together on this and other cold cases in an effort to provide closure to the families of those who have disappeared.
Anyone with information about the missing men can call police at 1-888-310-1122 or Crime Stoppers at 1-800-222-TIPS (8477).
