A Westlake Village man was sentenced to 15 years in federal prison for selling hallucinogenic mushrooms that were taken by a 17-year-old girl who was later hit and killed by a car on the 101 Freeway.

Stephen Thomas Roman, 31, pleaded guilty to three felony charges, including distribution of a controlled substance to a person under 21 resulting in death.

According to a criminal complaint filed Jan. 20, a group of young people, including 17year-old Victoria Nugent, were gathered in an apartment complex in Thousand Oaks in August 2004. One person called Roman and requested a drug called “magic mushrooms,” which he delivered.

After eating the mushrooms, Nugent began “behaving in a bizarre fashion,” according to a statement from the U.S. attorney’s office. Nugent’s friends attempted to lock her in a room, but she escaped, and while walking naked on the 101 Freeway in Newbury Park, she was struck by a motorist and killed.

Roman was sentenced by United States District Judge Percy Anderson, who also ordered the defendant to serve six years of supervised release after completing his prison term. Roman has been in custody in Ventura County since September 2008 on separate charges of selling the drug Ecstasy.

Before Anderson imposed the sentence, Nugent’s mother said in court that “no parent should have to bury their child.”

The case is “truly a tragic case for everyone concerned,” Anderson said.

In a post-arrest interview, Roman admitted he was the one who sold the mushrooms. Roman told investigators he had heard about Nugent’s death and how it related to the hallucinogenic mushrooms. When they asked him if he left the area after the incident, Roman admitted that he thought he needed to “lay low.”

The Van Nuys man who hit Nugent wasn’t cited. Lloyd Davis, a 43-year-old musician returning from a performance in Santa Barbara, wasn’t speeding and didn’t see Nugent.

Toxicology reports showed Nugent also had marijuana in her system.

Eighteen-year-olds Brian Mitchell and Alissa Ruef and 19-year-old Jonathan Martinez were charged with giving drugs to a minor. The three were at the apartment complex the night of the incident.

Manslaughter charges against Martinez and Mitchell were later dropped. Both pleaded guilty to the drug charge and were sentenced to 270 days in jail, but the sentence was suspended, and they didn’t serve any time, according to the Ventura County district attorney’s office.

Ruef pleaded guilty to lying to police about the events leading up to Nugent’s death and was put on three year’s probation.
