(CNN) Two young murder suspects found dead after an extensive manhunt apparently killed themselves, police in Canada said Monday.

Autopsies confirmed the bodies found last Wednesday in northern Manitoba are those of Kam McLeod, 19, and Bryer Schmegelsky, 18, according to the Royal Canadian Mounted Police.

"The RCMP can also confirm that the two died in what appears to be suicides by gunfire. While both individuals were deceased for a number of days before they were found, the exact time and date of their deaths are not known," the law enforcement agency said in a statement. "However, there are strong indications that they had been alive for a few days since last seen in July and during the extensive search efforts in the Gillam area."

Authorities said next of kin have been notified and offered support.

Two firearms were found with the teens and forensic analysis is underway to confirm whether they are connected to the three British Columbia homicides, the RCMP said.
