This is a trick question, considering there is no physical evidence that connects anyone to the crime with 100% certainty -- and yes, that includes TH and DJ. The hair attributed to TH could also be attributed to something like 800-900 people; it wasn't an identical match. You had a thumb print at the scene that was also never attributed to anyone, due (if memory serves) to it not being in good quality.
Circumstantial evidence (since you're evidently too lazy to simply read through these threads): the blue drop of candle-wax found on one of the shirts of the victims, and the blue candle found to belong to DE and DT. The fact that JB not only traded away weapons (a pick-ax and a knife) just after the murders, but also changed the black laces in his combat boots to new ones -- MM was tied with a black combat-style-length shoe lace that was never traced back to a source shoe, unlike the other two victims, who were tied with their own shoe laces. Also, JM's own, multiple confession fall in this category. In addition to the fact that, none of them had alibis (contrary to what PL and Bob Ruff will tell you) that could hold up in court.
Also, there's fiber evidence. Fibers recovered from the victims matched certain fibers found in JB's trailer (the source was a robe from his mom) and other fibers matching ones on MM matched the fibers of a green shirt that belonged to DE.
You also have BL's police interview, corroborating JM's involvement; in addition to JM's step-mother's account of JM having night terrors after the murders.
JB's entire alibi was that he was mowing his uncle's lawn, but his own uncle says this didn't take place the day of the murders. His alibi also consists of DE and DT being with him and going to the laundromat to call for a ride home (which was blocks away), even though JB's Uncle had a telephone and let DE inside his home on multiple locations. This is why JB's own lawyers wouldn't even let him testify; because they knew his alibi was garbage and would get shredded during cross examination.
There is probably more; this is just off the top of my head.
