In the weeks before he killed his mother and then took his life, 31-year-old Bertrand Pages talked with friends about predictions that the world would end with the culmination of the Mayan calendar, authorities said.

“We’ve had people tell us that with it being on radio and television about the whole Mayan calendar and the end-of-the world predictions, that he talked about it a lot,” Dorchester County Sheriff’s Capt. James Nettles said. “But we can’t say definitively yet whether that had anything to do with the actual homicide.”

Dorchester County deputies were called to the home of Pages’ 61-year-old mother on Dec. 20 after his brother found her dead inside the Brandywine Drive home. Lynda Pages had been shot once in the eye, according to the county coroner’s office.

The following morning, investigators found Bertrand Pages dead inside his vehicle, parked outside a Chili’s restaurant on Dorchester Road in North Charleston. He apparently died from a self-inflicted gunshot wound, according to Dorchester County Coroner Chris Nisbet.

His body was found the same day that the Mayan calendar came to a close, marking the end of a 5,125-year cycle known as the Long Count. The Mayans left few hints as to what would happen next, giving rise to a number of doomsday prophecies that didn’t pan out.

Bertrand Pages had expressed some concerns to friends about the impending end of the calendar, but investigators don’t know if that played any role in the murder-suicide, Nettles said.

His brother told authorities that Pages had been having personal problems.

Nettles said Bertrand Pages apparently had some relationship issues, had struggled with alcohol and was on medication of some sort. Other than some minor traffic citations in Florida, he had no prior criminal record, Nettles said.

Investigators are still interviewing witnesses, but they don’t what happened in those final moments before Pages killed his mother. “Unfortunately, there were only two of them there when it happened,” he said.

Investigators suspect a pistol was used in both shootings, but they are still waiting on State Law Enforcement Division tests to confirm that, Nettles said.

It remains unclear where Bertrand Pages got the gun, he said.
