Broken windows are seen on the 32nd floor of the Mandalay Bay Resort and Casino after Paddock sprayed bullets onto the Route 91 Harvest country music festival, killing 50 people.
An additional person of interest was identified in the days after gunman Stephen Paddock carried out the Oct.1 massacre on the Las Vegas Strip, newly released court records show.
A judge on Tuesday unsealed nearly 300 pages of search warrant records, including a document naming Douglas Haig as a second “person of interest” in the slayings, the Las Vegas Review-Journal reported.
Paddock’s girlfriend, Marilou Danley, was previously named a person of interest in the investigation into the massacre.
“Until the investigation can rule otherwise, Marilou Danley and Douglas Haig have become persons of interest who may have conspired with Stephen Paddock to commit Murder with a Deadly Weapon,” the Metropolitan Police Department document read, according to the Las Vegas Review-Journal.
Efforts to reach Haig Tuesday were unsuccessful.
Clark County Sheriff Joe Lombardo noted on Jan. 20 that the FBI had opened an investigation into an unnamed person of interest. He made clear, however, that Paddock had been the only shooter.
"I know and believe there was only one suspect who killed 58 people and injured hundreds more," Lombardo said. "All the evidence recovered in this case supports that theory. There was one shooter in the 1 October massacre. There was only one person responsible, and that was Stephen Paddock."

Lombardo has said that he does not expect charges to be filed against 62-year-old Danley, who was in the Philippines at the time of the attack.
Authorities have yet to determine the killer’s motive for opening fire on concert-goers. He spayed more than 1,000 bullets into the crowd from the 32nd floor of the Mandalay Bay Resort and Casino.
Investigators discovered a trove of weapons, including 12 rifles that had been fitted with "bump stocks," in the suite. The device allows semi-automatic weapons to function like automatic guns.
Paddock had acquired his arsenal of weapons legally.
"Paddock did not commite a crime until he fired the first round into the crowd at the Las Vegas village," a preliminary report stated.
The gunman shot and killed himself before authorities reached him.
