The amended death certificate for 19-year-old Alex Haas list "asphyxia due to fresh water drowning" with a secondary notation of "acute methadone intoxication."
The amended certificate of death for 19-year-old Tim Coleman is listed as "undetermined" with a notation of the possible involvement of electrocution by lightning and/or acute methadone intoxication.
