(CNN) Police executed a search warrant Thursday morning to comb through the home of the couple who raised $400,000 for a homeless Philadelphia man.

It's the latest twist in an escalating feud over the money and what happened to it.

Kate McClure and Mark D'Amico have been embroiled in a legal fight with Johnny Bobbitt Jr. after they started a GoFundMe account for him. They said they were touched by his kindness after Bobbitt gave his last $20 to McClure for gas when she became stranded on Interstate 95 in October.

According Florence Township, New Jersey, police Chief Brian Boldizar, the warrant was for a search of a property belonging to McClure and D'Amico.

In a statement, Burlington County Prosecutor Scott A. Coffina confirmed a search warrant had been executed "in connection with a criminal investigation into the Johnny Bobbitt matter" but said the couple have not been charged with anything.
