 Minnesota authorities are urging families of missing persons to provide DNA samples in an effort to match their DNA to unidentified remains. The Bureau of Criminal Apprehension exhumed the remains of three men and two women last summer. Their identities were not known when they were buried. BCA officials say a DNA sample from a close family member could be the first step in getting some answers. The BCA is holding events statewide where close family members of missing persons can provide DNA samples. One of the events is set for Bemidji tomorrow, July 19th from 4.30 to 6.30 p.m. at the BCA Bemidji Regional Office. To respect their privacy as they go through this very personal process, attendance at this opportunity is limited to families of the missing and there will be no media access during this time. Family members should bring the following items if available. The name of missing family member, date of birth, photos, dental records, items which may contain the missing persons of DNA such as a toothbrush or hairbrush, and the exact or approximate date and location they went missing. The BCA began a larger effort to identify remains in 2013. Since then, five people have been identified through DNA testing.
