Brian Laundrie, the sole suspect in the death of Long Island native Gabby Petito, died of a self-inflicted gunshot wound to the head, a lawyer for the Laundrie family said Tuesday.
“Chris and Roberta Laundrie have been informed that the cause of death was a gunshot wound to the head and the manner of death was suicide,” attorney Steve Bertolino told The Post. “Chris and Roberta are still mourning the loss of their son and are hopeful that these findings bring closure to both families.”
A forensic anthropologist determined the manner of death to be suicide.
It is unclear where Laundrie got the gun or if it was recovered from the scene where his remains were found.
