Concerning " crackpot theories" many of which were initially suggested in news reports before linked here, possibly for the same reason - because people could not, or would not state the obvious.
The Rabbi theory was really crackpot, imagine suggesting that they would suggest, using a cattle prod to force men into giving their wives a get, ridiculous!
Car rage theory was pretty nuts too, who has ever heard of someone "going postal" just because they got cut off ?
Truly a crackpot theory?
Upstanding family, angry their trophy of a baby girl, cannot steal kids from their loving father for g.ma's sake, so wealthy dentist brother, dating Latin King's gang member's ex- girlfriend and baby mamma, hires said gangster, breaks up with g.friend, who goes back to gangsta, arranges a hit, whereby he and a buddy go shoot a stranger, a nice guy teacher/lawyer and father, twice in the face at close range, while the hit-men's getaway car, a Prius, waits outside the victim's house.
The victim actually initially survives, but the ambulance comes too late, because they think it is not an emergency.
Truth can be stranger than fiction, there really are no "crackpot theories " until proven wrong.
All alleged, imo, speculation.
