Bethlehem police say they have finally tracked down the man they nicknamed the "Hammer Slammer," a suspected serial windshield smasher who had drivers across the Lehigh Valley nervously checking their cars for months. Grant Chase, 37, of Hellertown, was arrested on March 23 after investigators say they pieced together a pattern of damage that started last fall and picked up speed through the winter, as per 6abc Philadelphia.
Investigators executed a search warrant at Chase’s Hellertown home on March 18 and say they found evidence tying him to the string of incidents. He was arraigned in Bethlehem on a criminal mischief charge and his bail was set at $50,000, according to 6abc Philadelphia.
The vandalism in Bethlehem was reported between Dec. 3, 2025 and March 22, and police say most of the cases happened on east-side blocks. Surveillance video allegedly shows a person walking through neighborhoods overnight and swinging what appeared to be a hammer at parked cars, and officers say the suspect seemed to favor darker stretches of roadway without city cameras.
What The Charges Could Mean
Under Pennsylvania law, criminal mischief is graded by the dollar amount of the damage. It can be charged as a third-degree felony if pecuniary loss exceeds $5,000, while lower totals are treated as misdemeanors or summary offenses. Judges can also order restitution to cover repair costs. The details on grading and penalties are spelled out in Pennsylvania General Assembly statute 18 Pa.C.S. 7 3304.
How The Spree Affected Drivers
Police say that one night between March 21 6 saw eight cars damaged, with repair bills totaling about $8,000, and investigators estimate the regional damage across the spree at "several tens of thousands of dollars." Footage from multiple sources helped detectives connect the different incidents and move the case forward, according to 6abc Philadelphia.
What Comes Next
Chase remains charged in Bethlehem while investigators and prosecutors review the evidence, and court records did not list a follow-up hearing as of the latest reports. Police are urging residents to keep an eye out for suspicious activity and to check any home surveillance footage if they suspect their vehicle might have been targeted.
