Other commenters who claim to be relatives of Dwayne's wrote tributes to him, and one post came from a woman who said she was his niece.

That poster stated that Duane and his siblings had made the best of their lives, despite the fact that growing up, circumstances had been fairly difficult.

In January 2016, so just a few weeks into the investigation, the case took a more serious turn when authorities formally charged both Jennifer and Robert with murder.

They were both still out on bond for the previous exploitation charge, so law enforcement had to find out where they were and basically re-arrest them for the new murder charge.

According to a news release from the GBI, on January 12th, Jennifer was apprehended at her home in New York, but it took investigators more than a week to track Robert down.

He'd gone to be with family in Eastern Tennessee while out on bond for the exploitation charge.

He was actually from the Knoxville area, and that's also where his ex-wife and kids lived at the time.

According to court documents, the US Marshals had made contact with him over the phone a few times and set up appointments for him to turn himself in, but Robert never showed up.

So authorities were once again forced to surveil locations associated with him.

And then finally on the 21st of January is when they found him and made the arrest.

Nearly a month later, in mid-February 2016, Jennifer's lawyers filed a motion for a preliminary hearing, but that proceeding didn't actually happen until a few weeks later on March 2nd.

The only witness who testified at that hearing was a Georgia Bureau of Investigation agent named Steve Rogers.

Rogers had only worked for the GBI for about five months before Dwayne's case hit his desk, but prior to coming on board with the agency, he'd been employed as a deputy with the Walker County Sheriff's Office for about 20 years.

Rogers testified about how the Fort Oglethorpe Police Department had contacted him for assistance after finding Dwayne's body because they wanted help with the investigation and for GBI resources to come in.

When asked what he believed the motive for the crime was, Rogers testified, quote, Mr. Mott and Mr. Brooks just got tired of having to deal with Mr. Hollenbeck's disabilities, end quote.

Under oath, he went into detail about how the investigation had revealed Jennifer and Robert had used Dwayne's money and bank card to buy meth.

He said they'd also been seen by a witness striking Dwayne.

Now, Dwayne's toxicology results did show he'd consumed quite a bit of meth prior to his murder.

But it seemed the majority of the drugs that were purchased during the trio's travels were meant for Robert and Jennifer to take back to New York and resell.

On cross-examination, the defense pointed out rather candidly that there was no way Agent Rogers or any other investigator could prove that Dwayne had been forced to go on this road trip, or that he'd been forced to use drugs or take money out of his bank.
