(CNN) -
Brian Laundrie committed suicide by shooting himself in the head, a lawyer for the Laundrie family told CNN.
"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," said attorney Steven Bertolino.
"Chris and Roberta are still mourning the loss of their son and are hopeful that these findings will bring closure to both families," he added.
Laundrie was found dead at the Carlton Reserve in North Port, Florida, in late October.
CNN has reached out to authorities for further comment and has followed up with the family's attorney about how Brian came to be in possession of a gun.

Bertolino has told CNN in the past that he represents Laundrie's parents and Brian.
