“Brian Laundrie’s autopsy has not provided a manner or cause of death, and his remains are now being transferred to an anthropologist,” Bertolino told CNN.
A Wyoming coroner determined Petito, a Long Island native, died from homicide by strangulation, but few other details in the case have been confirmed.
Laundrie was considered a person of interest in the Petito case. His disappearance last month prompted a manhunt.
A public viewing for Petito was held on Long Island last month.
