You distort the representation. Only 4300 per year are attributed to homicide. That would only be 25%, a believable number. The remaining are attributed to drunk driving and the like
A few weeks ago, I saw a breakdown of the study that congressman King refers to. The methodology used looked valid. I did not verify the base numbers in any way, so I would not take the results as Gospel. The study did seem worthy of peer review for validity and after seeing the components they were assessing I would not have a hard time believing the results.
Twenty five percent is NOT a believable number. And Illegal is not nearly ten times as likely to commit murder.
Now I would believe that the ~4% of the population which are Illegal might commit 5-6% of the murders but not 25%.
