ROSEVILLE (WKZO) -- Authorities will be at a Roseville home Friday as they continue to investigate a tip about missing Teamsters boss Jimmy Hoffa.

Police don't believe an anomaly found underneath the home's driveway with radar is linked to Hoffa, but a soil sample will be taken and sent to a forensic anthropologist.  If traces of human remains are found in the soil sample, the driveway will be then be excavated.

Hoffa disappeared from a Bloomfield Township restaurant in 1975, and after thousands of tips and several searches his remains have not been found.
