MERRICK - A husband and wife from Merrick say they are still recovering from yesterday's manhunt for suspects in a home invasion that unfolded in their own backyard.Margaret and Thomas Harrison say they were drinking their morning coffee when heavily armed police officers came storming onto their property. "We had no idea what was happening at first, we just heard the helicopters," says Margaret Harrison. Just steps from the Harrisons' back door, a man suspected in a Bellmore home invasion was hiding from police in the brush.Police eventually caught the man, along with three others. They say the last suspect to be captured had stopped at a bar in Wantagh and then called a local cab company. By that time, authorities say they had already notified businesses to be on the lookout for suspicious behavior. When the man asked to go to Brooklyn, someone at the cab company realized he might not be a local resident and alerted police.All four of the suspects are from Brooklyn. They are expected to be arraigned tomorrow on first-degree robbery charges. As for the Harrisons, they say they are just glad that the manhunt ordeal is behind them.
