The title of a recently released CBS News article about Yale lab technician Raymond Clark III murdering Annie Le, a graduate student at the same university is "Report: Yale Suspect Tried to Hide Blood". This is otherwise known as tampering with evidence.

The sub-title is: "Suspect's and Victim's DNA found in crawl space of lab, official says". So the blood of Jonathan Clark III was found on Annie Le.

The critical sentence is "The official said (that) Clark tried to hide blood-spattered equipment and cleaned up areas Le was in before she vanished Sept. 8". This is known as covering up evidence.

A law enforcement official, speaking on the condition of anonymity said that "YALE WORKERS told police that Clark was a "CONTROL FREAK" who CLASHED with scientists and their proteges in the lab where they both worked at the Ivy League school". Being a "control freak" is undesirable as is often "clashing" with others.

Yet another critical/revealing sentence is: "As for motive, some believe Clark may have gotten into with Le over lab procedures". This is an EXPLANATION, not an alibi/excuse.

The roles that Clark and Le played may well have also been a contributing factor. "As an animal technician, Clark CLEANED CAGES and FED THE ANIMALS that Le and the other researchers used". "Le's work at the university involved experiments on mice that were part of research into enzymes THAT COULD HAVE IMPLICATIONS FOR TREATMENT OF CANCER, DIABETES AND MUSCULAR DYSTROPHY while Clark's technician job involved CLEANING FLOORS AND MOUSE CAGES". So perhaps socioeconomic status was a factor here. It seems as if Raymond Clark III is not very high class. Again, this could be part of the puzzle but again, this is not an excuse (i.e. Raymond Clark III is poor or he is not as well off as Le, so he should be excused for stuffing somebody into a wall: ABSOLUTELY NOT).

Some of the reactions from people who worked in the lab were surprisingly nonchalant. According to Kristin Dugan, "who works in the building where Le was found dead", "Things happen; you can't stop evil". This is not true. If Dugan was paying attention to what was going on around her (i.e. Clark's suspicious behavior), she should have done something like call the cops. "IF EVIL IS GOING TO HAPPEN, IT'S GOING TO HAPPEN ANYWHERE". This is incredible. How can Dugan possibly see someone WORKING IN THE SAME LAB GET STUFFED INTO A WALL AND NOT FEEL ANYTHING? This is incredibly insensitive.

According to legal analyst Lisa Bloom, speaking on "The Early Show", "It's not an element of murder or any homicide crime. Sure, they'd like to have it, because a jury is always going to be curious as to what the motive is. But when we have a mountain of physical evidence which sounds like what we're gathering here now, they certainly don't need to have motive". Perhaps this should take us back to the 2007 Virginia Tech massacre in which 32 people (25 students, 7 professors) were killed. People assumed that the killer, Seung Hui-cho, was in a romantic relationship with his first victim (Emily Hilscher) although people who knew Hilscher insisted that this wasn't true because Hilscher had a boyfriend. So perhaps Raymond Clark was jealous of the relationship between Le and her fiance? Of course, we will never know the answer to this question. We can only speculate.

Meanwhile, two friends of Raymond Clark III were surprisingly supportive of him despite the fact that he has been charged with a grisly killing. Frankly, they seemed to be stunned and at a loss for words when appearing on CNN's "Larry King Live". According to Bobby Heslin, "That's not the Raymond Clark I talked to my whole entire life". He seems quite adamant and defensive.

Maurice Perry sounded more disappointed and surprised than angry: "I just can't picture him doing something like this".

These are Raymond Clark's friends who are obviously biased. We can only wait and reserve further comment until the legal process runs its course.
