Cindy Crawford said she was "beyond heartbroken" following the death of her son, Presley Gerber, who died in September at the age of 27.
Los Angeles authorities have opened an investigation into the circumstances of Gerber's death, which law enforcement officials are treating as a suspected overdose. Details about the findings of the inquiry have not been publicly released.
Crawford's statement expressing profound grief came as family members and others close to Gerber cope with the loss. The family has not disclosed further information about the death or the ongoing investigation.
Local investigators said they would release more information as it becomes available while the inquiry continues. The case remains under review and officials have urged respect for the privacy of those affected.
