Three young adults and a juvenile face criminal charges stemming from vandalism that caused heavy damage late last spring at a local park in Bucks County. 20-year-old Jacob Grussenmeyer of Northampton Township, 19-year-old Colin O’Neal of Washington Crossing, 18-year-old Max Rosen of Newtown Township and an unnamed 17-year-old from Newtown Township are charged with criminal mischief and other offenses.  They are accused of smashing holes in the walls on a building housing restrooms at Roberts Ridge Park, on Frost Lane near Goodnoe Elementary School in Newtown Township.  They also allegedly ripped a door off the hinges, cracked solar panels in the roof and damaged a pavilion roof.  Trash was strewn around a playground, and equipment in it was broken.  The cost of repairing the damage is estimated at about $20,000.
