The explosions my wife heard were on the previous Monday morning.
The link you listed is a repost of the article on this thread. If I'm reading this correctly 18wheeler said the incident his wife experienced was on 10/3/05 - 8 days prior, and at a different apartment complex...
"My wife is a graduate student at UCLA and has an apartment at Weyburn Terrace, about two blocks south of Midvale Plaza. Her apartment is across an alley from Warren Hall, which I understand is a biochemistry building. She called me about 1AM Monday morning, 10/03/05, in a panic."
Very suspicious to say the least. Most disturbing is the lack of follow-through by the police on this...
