Authorities are drilling into a concrete floor of a shed in suburban Detroit to determine if it covers the final resting place of Teamsters boss Jimmy Hoffa.

Hoffa disappeared in 1975. The latest effort to find his remains is in a modest residential neighborhood in Roseville, outside Detroit. Crews began drilling into the concrete Friday to take a soil sample.

The shed is attached to a driveway where a recent radar test revealed a shift in the soil. The new search is related to a tip from a man who claims he saw a body being buried under the driveway 35 years ago. He thinks it might have been Hoffa.

Police Chief James Berlin says results of the soil samples could be ready by Monday.

Patricia Szpunar says the search to find what could be remains of former Teamsters boss Jimmy Hoffa has imprisoned her in her own suburban Detroit home.

Szpunar tells The Associated Press Friday that the Roseville home she's lived in for 24 years has been turned into a "three-ring circus" by onlookers and media members who gawk and take photos.

Authorities were taking soil samples from beneath Szpunar's driveway and a backyard shed Friday. The samples will be sent to a forensic anthropologist and tested for human decomposition. Results aren't expected before next week.

Szpunar says she wants to be left alone. When asked if she thinks Friday's search will end her misery, she says: "Get real."
