AUSTIN (KXAN) — An Austin man who pleaded guilty to selling fentanyl, leading to the deaths of two Westlake High School graduates, has been sentenced to 14 years in federal prison.

In May 2016, Sylvester Orlowski, 27, sold fentanyl to Clayton Wimberley, 26, and Anthony Zane Paduano, 25, both graduates of Westlake, leading to their deaths.

U.S. District Judge Lee Yeakel, in an order Thursday, said Orlowski will pay restitution to the families of both victims to cover funeral expenses. He will be placed on supervised release for five years after completing his prison term.

On Aug. 10, Orlowski pleaded guilty to one count of possession with intent to distribute fentanyl, causing death. By pleading guilty, he admitted to selling fentanyl in powder form to Paduano. Orlowski said he had to use Narcan to prevent the death of his friend earlier in the year.

Police searched Orlowski’s home in the 6300 block of Oasis Drive on May 9 and found around 17.8 grams of fentanyl, drug paraphernalia for use and packaging, and money from the sale of fentanyl.

Fentanyl, a schedule II narcotic, is used for pain control and anesthesia. In large or concentrated doses, it suppresses the respiratory system and causes death.

Orlowski’s fentanyl source and co-defendant, Albert C. Picazo III, 29, pleaded guilty to the same charge and is awaiting sentencing, scheduled for Nov. 17. He faces up to life in federal prison.

The case was investigated by the Organized Crime Unit of the Austin Police Department.
