Son of supermodel Cindy Crawford and entrepreneur Rande Gerber died at a rehabilitation facility

The death on Sunday of Presley Gerber, the 27-year-old son of supermodel Cindy Crawford and entrepreneur Rande Gerber, is being investigated as a suspected overdose, according to police.

Gerber died at a rehabilitation facility, Los Angeles county medical examiner records show. An autopsy was performed, but more testing was required before investigators could give a cause of death for Gerber, which the medical examiner did not immediately do.
