The F-B-I is back on the case of two armed fugitives from Alread who escaped federal, state and local authorities last week. An investigator asked the F-B-I to help examine two computers and phone records from the home of a missing couple who lived near the fugitives. Theodore and Ann Throneberry disappeard from their home in a remote part of the Ozark Mountains on March Seventh. Their reclusive neighbors, Mark Holsombach and William Frazier, were the last people seen with the Throneberrys, and when police went to question them last week, a gunfight ensued. The F-B-I and A-T-F joined state and county authorities to try to surround the men, but they got away. Both men were also wanted on several arrest and bench warrants. They had a stockpile of weapons and had set up bunkers throughout their 30-acre forest property.
