One of the sources in the Us story says Odom is "beside himself" with grief over this latest tragic loss of life.
Heyward's final Instagram post was a 2007 image of Odom with a group of friends including himself and Sanghouthai. Heyward wrote, "#RIP To my big brother Jamie who always brought light into any room he walked into and laughter as well at all times J you will always be missed. Family for life. #BandofBrothers #tbt"
