they are very hard to catch...seems most of the times in the states it is an accident...like they get pulled over for some minor offense or some shit. And also correlating these murders to the same person really take like the FBI type dudes. Something like 95% of murders in rio go unsolved.
That's cuz they don't want to devote the resources necessary to have the proper evidence to convict these low lifes. Call it a form of population control. Now if it happens to someone important then that's a different story..
