MANASSAS, Va. (AP) — Virginia’s chief medical examiner now says it’s possible that a 15-month-old boy whose father is charged with his murder died of natural causes.

The Washington Post (http://tinyurl.com/ms3tmrn) reports that medical examiner William Gormley on Friday reversed a ruling that Prince Rams died by drowning in Manassas in 2012. Gormley wrote that the cause of death for the boy should be considered undetermined because a natural death can’t be ruled out.
