As that would beg the question, why would a complete stranger kill them all, and then himself? Again, not likely.
My bet is they already know the motive, but are clearly holding back at this point.
Exactly. Several people above have incorrectly stated that it was the stranger they picked up that did the murders, but it was NOT. It was one of the Navy pilots. All the indicators are pointing towards homosexual jealousy.
Don't know, as it seems this story/incident went into a black hole.
Updates to this story have been on the front page of every San Diego news outlet since it happened.
