GREEN BAY, WI (WTAQ) -  After more than six hours on the scene, Green Bay police were unable to locate three suspects who allegedly robbed a trailer park home with a gun in Bellevue Tuesday afternoon.  Police got the call a little after 5 p.m. to an area of Bellevue Street and Lilic Lane regarding three suspects, one white male and two black males who were last seen in the marsh area across from the Eastlawn Park on the city’s eastside.  Brown County Sheriff’s Lt. Tom Ziegle say the suspects got away with an undetermined amount of cash from a home in the Bellevue Trailer Park in Bellevue.  The men were tracked to the marsh area on foot.  That’s when they got a call from Carl Lyse, a homeowner across from the park, who says his 2-year-old daughter found one of the men squatting in his garage.  Lyse says he pulled out his pocket knife and the man took off running towards the marsh.  Other witnesses saw the men in the area.  Police were called in to help search for the three men, setting up a perimeter with numerous squad cars, flood lights, and thermal imaging from Green Bay Fire Department.  SWAT and K-9 units searched the field.  Green Bay Police Captain Brad Florence says the “swampy area with thick high vegetation made it difficult to travel and observe anything much farther than arms length.”  By about 11 p.m. authorities gave up their search.
