Toms River police say the red Porsche Boxster went out of control just after 6:30 a.m. Sunday. The car hit the center median, struck an embankment and went airborne into the building.
Police said two Toms River men, 22-year-old Braden DeMartin and 23-year-old Daniel Foley, were deceased when emergency responders arrived at the scene.
"I took the day off, so I just came and brought some flowers, and just trying to be there for my friend," said Jacob Palecki, who said he went to middle school with Foley.
Police said the structure, which was unoccupied at the time, had been deemed unsafe by a building inspector. Sgt. Vincent Padalino said the building, which is across from Hooper Avenue Elementary School, houses four businesses, including a counseling service and a real estate company.
"We lost a really good guy, and my heart goes out to his family," said Palecki. "He loved cars. He called it a "CarB-Q," and he had a bunch of cars, he had all his family and friends there, and they were all showing off the different kinds of cars they had. That's what really brought him joy.
Police have been taking measurements to see how fast the car was going, and are looking into alcohol as a possible factor. It's still not clear who the car belonged to.
