What would be the repercussions for an inmate handwriting a letter to a judge without legal council?

In a case I am following a person being charged with murder 1 hand wrote a letter to the judge likely behind his lawyers back. The defendant wrote very sloppily and misspelled the judges name. In the letter the defendant stated “I know you know the laws but I feel I have to exspress my concerns…” The defendant also mentions that he believes his right to a fair and speedy trial is being violated by being held for more than six months along with the bond being set at an unreasonable price.

Would this set the defendant back at all? Would the case be stalled even more or do you believe immediate action will be taken? I can provide more details about the case in a DM or chat.
