Per 
SCP-5257 is a 32 year old man who claims to be from 2291 and is a weapons expert able to kill anyone. Containment of 5257 lead to the death of two mtf squads and 30 civilian deaths none were injured. SCP-5257 is a Keter SCP and has been the reason for 7 containment breaches. 5257 has been hard to research as he hates being spoken to and has killed 98% of researchers who have tried talking to him. Do to his shoot first ask questions later approach to things he may be perfect for termination of certain SCPs. The only way that we have found that can contain SCP-5257 is by allowing him access to a hard target firing range. In the last containment breach SCP-5257 worked together with all computer SCPs most notably SCP-079 and he hacked almost every door and nearly escaped before 10 mtf squads injured him to the point of passing out. Attempts to use SCP-5257 to help with containment has led to the severe injury of 3 SCPs. Emergency containment procedures requires that SCP-5257 be shot multiple times where his important bones are and he is to be placed in a titanium and tungsten alloy box and should be given a few small hard targets. SCP-5257 was found in a small town in Iowa USA after police were killed and he was found sitting next to the bodies and he admitted to murdering them when asked why he did this he replied with “they got in my way, my mission here is simple and I do not need to be stopped I haven’t left here because I haven’t found anything to exploit yet.” If SCP-5257 is required to be terminated he should be placed in a acid bath as acid has proven effective at getting past SCP-5257’s healing systems.
