Samuel Haskell Jr. accused of three murders, but only one body recovered

Samuel Haskell Jr. was hit by three murders — even though police say they only recovered body parts from one victim — and now we know why.

Law enforcement sources tell TMZ that Haskell is charged with three counts of murder because of what witnesses told police and what police later found at his home.

Our sources say that the day laborers Samuel hired for take away garbage bags from his home are key to the case… they told police they became suspicious, opened a bag, saw body parts and took the bags back to Haskell.

We’re told biological evidence was also found in the home where his wife and in-laws lived before they went missing. Our law enforcement sources tell us the biological evidence comes from three different people. We don’t know the nature of the biological evidence, but we do know that police found blood in the house.

TMZ broke the story… Haskell is on video dumping what appears to be a heavy black bag in a dumpster near his home the day before someone discovered a dismembered body in a bag from the same dumpster.

TMZ also obtained footage of the day laborers taking three garbage bags from his home and driving away, before eventually returning the bags to his driveway. The workers then went to the police and Haskell drove his Tesla to a nearby strip mall and threw a bag in the dumpster.

The body found in the waste container has not been identified…but we’re told it’s a female. Haskell is accused of murdering his 37-year-old wife. Mayand her parents, 72 years old Gaoshan Li and 64 years old Yanxiang Wang.

Our sources say it will be virtually impossible for law enforcement to find the other bodies… especially if they are dismembered and dumped in the trash.

The problem… we are told that once the waste is emptied and taken to a landfill, it is very quickly dumped and buried… making it very difficult to identify the remains.

In fact, we’re told there’s a good chance none of the bodies would have ever been recovered if it hadn’t been for the homeless man who discovered the bag of body parts.
