A quadruple amputee wanted for questioning in the shooting deaths of his parents killed himself late Monday during a traffic stop in Tennessee.

Sean Petrozzino, 31, of Orange County, Fla., was last seen driving his father's truck. The bodies of his parents — Nancy Petrozzino, 64, and Michael Petrozzino, 63 — were discovered last week inside their home after Orange County Sheriff deputies were asked to do a wellness check, MyFoxMemphis.com reports.

Police in Memphis said officers initiated a traffic stop late Monday after observing a red 2012 Toyota Camry make a U-turn at Sam Cooper Boulevard and Tillman Street. As officers exited their vehicle, they heard a faint "pop" from inside the vehicle.

Officers then discovered the driver had an apparent self-inflicted gunshot wound and was pronounced dead at the scene. No other injuries were reported. A responding officer did not fire his weapon, MyFoxMemphis.com reports.

Petrozzino, who used prosthetics to walk, reportedly lost his hands and lower legs to bacterial meningitis at age 16.
