AUSTIN (KXAN) — A man facing charges in connection with the death of an Austin man in November is back in Travis County. An affidavit details why he was charged with murder after he was initially only charged with tampering with a corpse.

According to the Travis County Inmate Search, Gavin Roberts, 26, was booked into the Travis County Jail on Tuesday evening.

An attorney for Roberts was not listed online at the time this article was published.

Roberts was arrested on Nov. 23 in Colorado.

search warrant revealed that surveillance footage and cellphone records showed Roberts was with Justin Haden the day Haden went missing. 

Detectives with the Austin Police Department traveled to Colorado Nov. 30 to interrogate Roberts, where he at first denied knowing Haden’s whereabouts, an affidavit said.

However, after detectives presented evidence of Roberts being with Haden the night he disappeared, Roberts requested a map and circled a spot on Ronald Reagan Boulevard, then said he buried Haden under an overpass in the area, according to an affidavit.

Police found Haden’s body near Ronald Reagan Boulevard and Interstate 35 in Williamson County on Dec. 1.

An autopsy was performed on Haden’s body Dec. 2 and the cause of death was determined to be sharp and blunt force trauma. The manner of death was ruled homicide.

There were at least two sharp force-type injuries and multiple facial fractures, according to the affidavit.

While police were in Colorado interrogating Roberts, he explained that he and Haden got into an argument, and Haden grabbed a kitchen knife and brought it into the bedroom, the affidavit said.

Roberts told police that he took the knife from Haden and stabbed him, then stabbed him a second time after Haden “came at him again,” according to the affidavit.

Roberts also told police Haden went to get a cast iron skillet and came back into the bedroom, the affidavit said. Then Roberts said he took it from Haden and hit Haden in the face several times.

Police noted in the affidavit they believe it’s “improbable” that Haden was able to walk around the apartment after his initial injuries. Police only found blood in the bedroom, according to the affidavit.
