By the time federal agents reached the driveway outside the vice president’s Cincinnati home, a 26-year-old carrying a hammer had already crossed the fence line and, according to charging documents, started swinging at glass.

Prosecutors describe a deliberate attack on a protected residence. The defense describes a mental health emergency that had nothing to do with Vice President JD Vance or politics. The public record so far leaves both motive and the defendant’s mental state an open set of questions.

What Prosecutors Say Happened Outside Vance’s Home

According to a federal affidavit filed in recent days and summarized by Fox News Digital, William DeFoor is accused of running along the front fence of Vance’s Secret Service-protected Cincinnati residence before entering the property at the driveway.[1] The affidavit states that an unmarked federal law enforcement vehicle was positioned to block the driveway entrance.

Prosecutors say DeFoor was armed with a hammer and tried to break the driver’s side window of that vehicle. When agents ordered him to stop and drop the weapon, he allegedly ignored all commands and moved toward the front of the home.

Charging documents cited by Fox News Digital state that DeFoor used the hammer to strike and break glass across the front of the residence. The windows were fitted with government-owned enhanced security materials. Prosecutors value the damaged security assets at more than $28,000.[1]

After the glass strikes, DeFoor allegedly tried to flee on foot. Secret Service agents and Cincinnati police officers then detained him on the property, according to those same documents.
