The incident happened in an alley behind a bank she was cleaning in central Ohio.
Investigators hope to find Summer alive, but are considering the possibility she may have been seriously injured or killed.
Officials said nothing turned up from searches conducted Sunday in the counties of Hocking, Perry, Morgan, and Muskingum.
The Logan Police Department has received information that on Wednesday morning, March 23, around 10:00 - 11:00 a.m., roughly 12 hours after Summer's disappearance, individuals believed to be the Inman's, in their white Ford Crown Victoria, stopped at Pearl Road Auto Wrecking and Salvage in Cleveland, Ohio.
Investigators have learned that a man believed to be William A. Inman, told an employee at the business that he didn't like the wheels and tires currently on his vehicle and was looking to purchase four different wheels and tires for the same vehicle. The employee sold Inman a used set of four 16" wheels and tires and gave Inman a credit for the wheels and tires he turned in.
Inman was observed putting this new set of wheels and tires on the family's white Crown Victoria in the Pearl lot.
After a couple of hours, Inman had the wheels and tires on the white Crown Victoria and they left. Approximately four hours later, an unknown man came into the same business looking for four 16" wheels and tires for his Crown Victoria.
The man saw the four wheels and tires now in the showroom from the Inman's vehicle and purchased them. Because the purchase was made in cash, there is no record of the identity of the man who purchased the wheels and tires previously on the Inman's vehicle.
Investigators are seeking the public's assistance in identifying this man. The man was described as a white male, possibly in his 30's. Anyone with any information as to the possible identity of this man is asked to contact the Logan Police Department immediately at 740-385-6868.
Investigators continue to encourage the public to search their own property, focusing on those areas close to a roadway, or near bridges and overpasses, for any signs of recent suspicious activity or clothing items similar to those worn by Summer at the time of her abduction. If anything is found, please contact the Logan Police Department immediately at 740-385-6868.
