A man accused of drunkenly killing his identical twin brother in a freak accident while trying to parallel park a minivan has killed himself, authorities say.

Timothy Willgruber, 57, hanged himself in his home in Allentown, Pa., Lehigh County Coroner Scot Grim said. Police said Willgruber faced charges including vehicular homicide and drunken driving stemming from the death of his brother Thomas last month in Bethlehem.

Thomas Willgruber was guiding his brother into a parking space when Timothy Willgruber lost control, pinning him against another vehicle. Thomas Willgruber died later that night.

Bethlehem police Capt. David Kravatz says Timothy Willgruber was "devastated" after the accident. Family members say the brothers were best friends who rarely went a day without talking.

"It's a double tragedy for the family to lose a beloved spouse and father and to then lose a cherished uncle," Kravatz told the Allentown Morning Call. "I know he was distraught that his brother died in front of him."
