The second of two suspects has been arrested after they allegedly posed as utility workers to gain access to a couple’s Michigan home before killing the husband and leaving his wife restrained with duct tape, according to authorities.

The second suspect was taken into custody “without incident” Monday afternoon, according to an X post from the Oakland County Sheriff’s Office. Authorities identified him traveling in Plymouth Township and made a traffic stop, the post said. Plymouth Township is around 45 miles from Rochester Hills, where the killing took place.

The first suspect, Carlos Jose Hernandez, 37, was arrested in Shreveport, Louisiana, on Saturday. He faces charges of felony murder and unlawful imprisonment. Hernandez is currently being held in Caddo Parish, Louisiana, but the Oakland County Sheriff’s Office said it plans to extradite him to Michigan.

CNN has reached out to determine if the suspects have legal representation.

A charging document stipulates Hernandez committed the killing “in the perpetration or attempted perpetration of a robbery.”

Authorities said the two men arrived at the Rochester Hills home Hussein Murray, 72, shared with his wife on Thursday and Friday. On both occasions, the men posed as workers for DTE, a Detroit-based energy provider, and said they were there to investigate a gas leak.

On Thursday, the Murrays did not allow the men into their home. But when they returned on Friday, Murray “signed a piece of paper purportedly from DTE and escorted the defendant to the basement,” according to a Sunday news release from the Oakland County Prosecutor’s Office.

Then the two men returned upstairs, asking Murray’s wife “where the money and jewelry were,” the release said. They duct-taped her wrist and ankles, hit her across the face, and took her phone and watch before leaving in a truck with a DTE sign, according to the release.

Murray’s wife was able to call 911 and told officials she thought her husband may have been kidnapped, according to the Oakland County Sheriff’s Office.

Murray’s body was discovered in the basement, with his wrists and ankles also duct-taped, the prosecuting attorney’s office said.

“Because of the gruesome nature of the injuries, it was not immediately clear if he had been shot or bludgeoned to death,” the sheriff’s office said.

Murray’s death was ruled a homicide on Saturday by the Oakland County Medical Examiner, according to the sheriff’s office. His wife was hospitalized following the incident and has since been released, the sheriff added.

A doorbell camera video of one of the suspects wearing a respirator mask and identifying himself and another man as DTE Energy workers looking for gas leaks was released by the sheriff’s office on Friday.
