CNN reports that there’s more than pizza crust linking Darron Wint to a gruesome quadruple murder committed last month inside a Washington D.C. mansion. The blood from at least one victim was found on Wint’s shoes when he was arrested, according to law enforcement sources who spoke with the news station.

In court papers filed on Friday, police said that the capture and killing of the Savopoulos family in Washington, D.C. last week would have required more than one attacker, the New York Times reports.

Darron Dylon Wint was taken into custody late Thursday night, NBC Washington reports. He is charged with first-degree murder while armed.
