This keeps getting more and more mysterious. They've done the autopsy but are keeping the results a secret. However, there is no doubt it is a homicide:
Assistant Prosecuting Attorney Holly Curtis praised detectives, but said, “In order for criminal charges to be filed, there must be probable cause that a crime was committed and probable cause that a particular person committed the crime.”
She added that there is “no doubt” that Jodi’s death was a homicide but “at this time we cannot establish that a particular individual committed this crime.”
and
Jodi’s friends told police conflicting statements as to where Jodi planned to go after visiting her friends.
Some said she was going for a bike ride. Another said she was going home for supper. Another said she was riding her bike to a nearby store to buy a snack.
