Patrick Mikes has not been seen since Friday.
Now, police believe Mikes is dead. Sources say evidence points to Mikes' oldest son. However, police are not calling Patrick Mikes Jr. a suspect in his fathers' disappearance but a person of interest.
This comes after blood and other evidence were found in the basement of Mikes' Troy home. The Oakland County Medical Examiner says it is highly unlikely anyone would live through whatever happened in that basement.
Police now have video from a local store which shows someone buying cleaning supplies on Sunday.
Neighbors said Mikes, an avid bicyclist, left for a bike ride Friday. However, police said his helmet and bike shoes have been found at his home, and suspect he wouldn't leave for a ride without them.
Son charged with credit card fraud
Patrick Mikes Jr., 21, was arraigned Wednesday on three counts of illegally using a financial transaction device. He pleaded not-guilty and his bail was set at $50,000. He is scheduled to be back in court Aug. 13.
Mikes is accused of using a credit card that didn't belong to him at Great Lakes Crossing on July 26.
Police said the card the 21-year-old used did not belong to his father. It was his younger brother's card.
