That >40 hour lag time b/t when he supposedly left for school Friday morning and when his parents reported him missing late on Saturday night is deeply troubling, especially given the fact that per HD's mom, he had complained of not feeling well.
I don't know of many moms who wouldn't get worried if their son who had complained of feeling unwell didn't ever show up home from school.
To say his parents ain't making anybody's shortlist for Mother/Father of the Year is putting it kindly.
I really wish a reporter would ask LE if either of the parents attempted to contact any of HD's friends to track him down b/t Friday afternoon and Saturday night before they called LE.
If not, that's dreadful.
Self-harm, foul play by person(s) known to HD, HD meeting up with someone that Friday morning, all are possible scenarios here.
The fact that there have been no sightings of him since that morning doesn't bode well, whatever the reason for his disappearance.
