It may be three months before we know how the Broken Arrow teenager found at Fort Gibson Lake died.


Autopsy reports were expected Friday in 18-year-old Jarret Clark's death. Now the state medical examiners office says it will be about 12 weeks before they can determine an official cause of death.


The Oklahoma State Bureau of Investigation is still following leads as if it were a homicide investigation, but they say they don't know what they have at this point.


Meanwhile, friends have decorated Jarret’s car at his Broken Arrow home. They're remembering him for his happiness, competitiveness and his compassion for his mom and step dad. Jarret’s friend Eric Hansen: "And it makes it hard i guess, for me, to think about what his parents have to go through because not only did they lose a son, they probably lost a best friend through it all."


Funeral plans for Jarret are pending.
