If you want to turn grandma’s house into a meth lab, do what any respectable dope fiend would do – drug the old coot and cook up a batch while she’s on the nod.

That is exactly what Louisiana police say they discovered happened over the weekend in Arnaudville. According to reports, 35-year-old, model grandson Todd Richard had been drugging his 78-year-old grandmother on a regular basis so he and his friends could cook and smoke crystal meth in her attic.

However, it wasn’t until the water department came out to disconnect grandma’s service that she learned instead of Richard using the money she had given him – more that $7,000 - to pay her monthly bills, that junkie bastard and his speed freak friends had been smoking and snorting it all up. Of course, it was then that she felt like she had no choice but to rat out her thieving grandson to the police.

Richard was charged with cruelty to the infirm, exploitation of the infirm and several counts of distribution of Schedule II narcotics. He is expected to do some time in prison…and possibly get one hell of a spanking from grandma when he gets out.
