Serial Killers who have escaped prison to kill again?

[CameraSnap]

I recently watched this Video about serial killer John Straffen who escaped Broadmoor to kill again.

I can only think of Bundy as the other who escaped is there any other examples of killers going on a rampage after escaping capture?

While others may have escaped, many more have been released early or paroled and then went back to killing.

They may have killed again but we can't say for sure.

1-In 1721, Anne Bonny escaped jail while awaiting trial, perhaps due to a bribe, and was never recaptured.

2-In 1916, Carl Menarik, aka Frederick Mors, escaped from a secure mental hospital while awaiting deportation and was never recaptured.

Both are listed in The Encyclopedia of Serial Killers.
