Authorities in Northville and Farmington Hills believe separate assaults on women in those communities are related, though the targets appear random, they announced Friday. They are hopeful of getting leads from witnesses.
Chronologically the attacks began in Northville Wednesday morning.
A 69-year-old woman was heading home from the Northville Community Center.
She pulled into the driveway of her Lake Street home, and was getting out of the car when the suspect approached her. He carried a folio, and asked the victim if she would take a survey.
The victim was skeptical because the intruder carried no ID. When the victim asked for one, that was the last she remembers.
The suspect knocked the woman into unconsciousness. When she came around, she noticed that her wallet and some other items had been stolen.
The victim told police the assailant was driving a light-colored, possibly tan, sedan.
Hours later, that same day, a Farmington Hills woman was attacked.
The 42-year-old was assaulted outside her condo near 8 Mile and Grand River, at about 10:45 p.m.
The suspect did not attempt the survey ruse, but did swing a blunt object at the woman.
This time nothing was taken.
Despite the differences, the police think the same person is behind both assaults.
The second victim described him as a black male, about 35, tall with a medium build. He was driving a brown or tan Ford Taurus.
Anyone who has information on either incident should call the appropriate local police.
