Drug Charges Dropped Against Scott Weiland's Bandmate Tommy Black

Bloomington's Deputy confirms to ET that they won't pursue drug charges against the rocker.

Just two days after a report from the Hennepin County Medical Examiner confirmed Scott Weiland died of mixed drug toxicity, the charges against his Wildabouts bandmate, Tommy Black, were dropped.

Bloomington Deputy Police Chief Mike Hartley confirms to ET that they won't pursue drug charges against Black because "the bus was shared by a lot of people, and it would be difficult to prove" that the drugs belonged to the 47-year-old rocker. Black also shared the update on his Facebook page, simply posting a link to an article about the case.

As ET previously reported, Black was arrested earlier this month and taken to the Bloomington Police Department, where he was held pending charges for possession of a controlled substance. The arrest occurred immediately after police found cocaine on the tour bus and in Weiland's room, where the former Stone Temple Pilots and Velvet Revolver lead singer was found dead on Dec. 3 in Bloomington, Minnesota.

Weiland, 48, died with cocaine, ethanol and methylenedioxyamphetamine (MDA) in his system. His death was officially ruled as an accident, according to the medical examiner report that was released on Friday. It also called attention to Weiland's "other significant conditions," including a history of asthma, atherosclerotic cardiovascular disease and multi-substance dependence.

Following his death, Weiland's former bandmates, Eric Kretz and brothers Dean and Robert DeLeo, penned a message to the late rocker on the Stone Temple Pilots' Facebook page.

"Dear Scott, Let us start by saying thank you for sharing your life with us," the letter began. "Together we crafted a legacy of music that has given so many people happiness and great memories. The memories are many, and they run deep for us."

"We know amidst the good and the bad you struggled, time and time again," the post continued. "It's what made you who you were. You were gifted beyond words, Scott."
