Troy police have said they believe Mikes Sr. was killed in the basement of his home.
"Investigators are attempting to reconstruct a timeline of Patrick Mikes Jr's whereabouts from Friday July 27 to Sunday morning July 29 in order to assist in the recovery of the body," Troy police said in a statement.
The search is based on phone records of Mikes Jr. from Friday, the last day his dad was seen alive.
"Investigators have discounted Patrick Mikes Jr's report that Mr. Mikes left the home at 5:30 PM to go for a bike ride. Mr. Mikes was home Thursday night. Mr. Mikes did not show up for work Friday morning and has not been seen since that time," police said in a statement.
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.
