One of the challenges in covering a fast-moving story like the murder of Yale grad student Annie Le is separating rumor from fact and getting confirmation of developments in time for our often hourly live on-the-air updates.

Many but not all of the rumors in this case have proven true, including the fact that a lab technician has emerged as the “person of interest”, which as far as I can tell is modern time’s politically correct terminology for “suspect”.

Rumors that proved untrue: Annie’s body was in the trash compactor, and the prime suspect was a student.

Things I’ve heard and have been reported but police won’t confirm: Raymond Clark had scratches on his chest and failed a lie detector test; the blood-stained clothes found in the lab are his; he was angry at Annie for her treatment of lab animals, specifically mice and exchanged emails with her about the issue.

We’ve worked more than 60 hours over the past four days and still have a few hours left on this shift. It seems every time we think we’re done for the night there’s a new development and we have to rush back on the job. We’re all pretty beat but committed to seeing this story through to it’s conclusion, hopefully the arrest of Annie’s killer.

At a news conference late this afternoon, New Haven Police Chief James Lewis sounded confident but careful. If there’s a DNA match to Clark, an arrest warrant will be issued within a couple hours and “we know where Clark is at all times.”

He also insisted there is no tunnel vision and they’re not ruling anyone else out yet.

A straight shooter, Lewis had a quick response to a question about a prominent lawyer suggesting the search and seizure warrant already served on Clark might be unconstitutional.

“You get three attorneys in a room,” the Chief said “you get five different opinions.”
