Who Is Bobby Dassey? ‘Making a Murderer’ Fans Think He's Guilty of Teresa Halbach’s Murder

Making a Murderer part two spotlighted wrongful conviction attorney Kathleen Zellner and her latest suspect, Bobby Dassey. Dassey is the brother of Brendan Dassey, who was convicted of the murder of Teresa Halbach, along with his uncle, Steven Avery. Both men maintain their innocence though they're currently behind bars.

Many Twitter users are convinced, with Zellner's reasoning, that Bobby Dassey should be considered a viable suspect in the murder of Halbach. In fact, many believe he's guilty. Twitter feeds are full of mentions to Bobby Dassey's name, many of them framing him as a key player in Halbach's death.

“After watching the new episodes of Making A Murderer, I don't believe Steven Avery did it but I definitely think Bobby Dassey & Scott Tadych did it. Kathleen Zellner is an amazing lawyer,” a user shared.

Zellner attempted to introduce 2,449 pages of data download from Bobby Dassey's computer as evidence in the Avery trial, though her motion, and a new trial for Avery, was denied by the Wisconsin Circuit Court, according to a July article by Rolling Stone. The data show violent porn downloads by Bobby Dassey, as well as alleged evidence he was not asleep at a time he alleged on the day of Halbach's murder. Instead, the data shows he was online.

Bobby Dassey was used as a main witness in the case against his brother and uncle Steven Avery, but he is reportedly the last person to see Halbach alive. When a Twitter user asked Zellner why he wasn't imprisoned for the porn charges alone, she pointed to his past status in the cases.

“Good question. Remember he was the State's star witness. Perhaps he was pressured into that with threats of prosecution,” Zellner tweeted on Tuesday in a Twitter question-and-answer session.

The sexual violence found downloaded on Bobby Dassey's computer could serve as a motive for Halbach's violent death, appellate attorney Erica Suter told Rolling Stone. Twitter users agree, and many called Bobby Dassey a "pervert" and a "creep."

“The last three episodes of Making A Murderer part 2 really creeped me out. F*** Bobby,” a user said.

Viewers also applauded Zellner's hard work on the case. “Soooo I finished Making A Murderer in under 48 hours. Steven is definitely innocent. It was either Bobby or the ex-boyfriend. And I want Kathleen to run for president,” a user wrote.
