The family of a man found beaten to death in Lincoln Park is searching for answers.
"He was the most gentle, caring person in the world," said his mother Kim Bacia, who spoke out for the first time since her son's murder. "We're just devastated and our hearts are broken."
He was pronounced dead at a local hospital.
Family members said the last 10 days have been a blur.
"We're just stunned," said his father Chester Klepacz. "It's like a nightmare."
Friends and family have taken to social media in search for answers, creating a Twitter and Facebook page titled "Justice for Jacob."
They believe someone out there knows something.
"It helps us," said Bacia. "It won't bring him back but nobody needs to go through this pain. You think you'd know what it would be like if it happened to you, but you dont."
They point to clues on Klepacz's Facebook page just hours before his death.
He posted "Random dude party," and checked in at Dugout Sports Bar and Grill in Wrigleyville.
"We're just trying to survive right now without him," Bacia said. "Just keep thinking he's going to come home and he's not."
