Mark Wilmens

Mark Wilmans was Ice Pick Thompson, a serial killer in New York in 1932. Mark ended up relinquishing the title of Ice Pick Thompson to Raz Smith.

Background
Mark's mother Paula worked for Szilard Quates, who was rumored to be her father. Among her responsibilities was to look after the immortality elixir he was developing. Paula considered having her son drink a bottle of the elixir she kept, but decided to bury it at her husband's grave instead. Knowing the kinds of things Szilard's men would do to have the elixir, Paula told her son to reveal the location of the bottle if he was ever interrogated about it.

In November 1930, after Szilard's death and the fire that destroyed most of the bottles of elixir, a group of Szilard's men kidnapped and tortured Paula. Her corpse was dumped in the Hudson River.

Paula had hidden her son in a closet when the men first came to their apartment. Mark stayed there for two days before he was found by police officers. He identified his mother's body, which was covered in wounds created by an ice pick.

1932
Mark becomes the serial killer Ice Pick Thompson, a moniker coined by Carl Digness because he stabs his victims with an ice pick to the point where it looks like they were shot by a Thompson submachine gun. Mark's only targets are the men who tortured and killed his mother.

When Mark is targeting Lester, he mistakenly attacks Elmer C. Albatross because they are dressed the same way. Mark realizes his mistake and runs away, horrified at the thought of having stabbed an innocent bystander. Elmer finds Mark standing on the edge of the Brooklyn Bridge; in their ensuing conversation, Elmer tells Mark that he will not try to stop him from committing suicide if that's what will make him happy. Mark explains that this is not the case, though he still doesn't want Elmer to interfere. Elmer decides that the best thing to do is to demonstrate how a fall from such a height would be a painful way to die, and reveals his immortality to Mark in the process.
