Woman tried to use acid and alligators to get rid of husband's ex-wife

After Grant and Amanda Hayes killed Grant's ex-wife, Laura Ackerson, cut her body into pieces, and attempted to dissolve the remains in acid, they threw her dismembered remains into an alligator-infested creek to get rid of the evidence. Those are the grim details of Ackerson’s 2011 murder that a Texas jury heard this month before convicting Amanda Hayes of tampering with evidence. She has been sentenced to 20 years in prison.
