Police are asking for help finding the man they say is responsible for a total of four "push-in" home invasions in the Sedgwick and Eastwood sections of the city.
On Friday police say Mario Clark struck twice, both times in the city's Sedgwick neighborhood. In at least one of the cases police believe he had a handgun, though never showed it. He was known to some of the victim's in the Sedgwick area because investigators say he had done work for the homeowners in the past - mowing lawns or shoveling snow.
In all the cases police say the man approaches the home, knocks or rings the doorbell, then pushes his way in to demand money.
CNY central has also learned that Clark spent 5 years in state prison for robbery back in the 1990's.
