The family of a West Allis man brutally beaten outside a bar and left for hours is begging for help as they try to find out how Chadd Dahlberg wound up in intensive care.
His injuries are so severe he can't speak for himself.
"He can't really communicate with us. I don't know if he knows who I am, if he knows who his son is," said his younger sister Annmaree Dahlberg.
Annmaree said the 37-year-old is in the hospital suffering from a traumatic brain injury.
"They had to remove a rather large piece of his skull...and he had fractured ribs," Annmaree said.
Jason Rengstorf is charged with aggravated battery after a fight outside One More Tavern in West Allis last month. The victim's sister said video from inside the bar near 75th Street and Beloit Road that night shows her brother drunk and asking to leave. He came back later and was asked to leave again.
"He went back outside and two people followed him and then at that point I know he was assaulted," Annmaree said.
In the criminal complaint, one of the men said Dahlberg threw a punch and then Rengstorf punched him in in the chin. It says police found the victim "nearly four hours later" with "abrasions and swelling to his nose and lips."
"You ask him to leave and leave it at that. You don't follow him out and assault him to the point of death," Annmaree said.
His family doesn't believe one punch could cause so much damage.
"I want people to hold these people accountable that did this to him," Annmaree said.
The family is asking anyone with information to come forward. You can contact West Allis Police at (414) 302-8000 or the Dahlberg's directly at firstname.lastname@example.org
The Dahlberg's have a GoFundMe Page set up to help with medical expenses.
