After police were notified, they traveled to Gary’s home in Torbay and discovered that he had indeed rigged the residence with a bomb. The device was made up of two 180-kilogram (400 lb) propane tanks and could have destroyed the entire neighborhood if it went off. However, there was no sign of Gary or his three sons, and they have not been seen since. One year later, an engine belonging to a 1989 Ford Tempo was found in the ocean off nearby Red Head Cliff. This led to speculation that Gary may have committed a murder-suicide by deliberately driving his vehicle into the ocean with his three sons inside. However, it is unknown if the engine actually belonged to Gary’s Ford Tempo.
