SAN DIEGO -- The owner of a home where witnesses said several teens were drinking prior to a fatal car crash told 10News he is not to blame for the situation.

The crash in Rancho Santa Fe killed Alex Capozza, a 17-year-old Torrey Pines High School student, and sent another to the hospital. Homeowner Michael Flynn said he did not provide anyone at the party alcohol.

On Wednesday, 17-year-old Branden Butler appeared in juvenile court. Butler is accused of driving while intoxicated in the fatal crash that happened early Sunday morning. The Torrey Pines High School senior will remain in custody and faces felony DUI and manslaughter charges.

Witnesses said Butler, Capozza, 17-year-old Jamie Arnold and two other teens were drinking and partying at a $5.7 million mansion in Rancho Santa Fe before the incident.

10News' Jennifer Kim asked Flynn, "Was there a party here Saturday night?"

Flynn replied, "First of all, there was no party. It was a get together."

"Were you here?"

"No, I was out of town."

"Oh, you were out of town. Did you supply the alcohol?"

"No, no."

According to San Diego County's social host ordinance, hosts could face penalties for allowing underage drinking on their property. When it comes to knowing what is going on and what kind of alcohol is inside a home, authorities said the responsibility lies with the property owner.

"If I'm a homeowner, I'm going to know what's going on in my property. It's unusual for me to believe I would have underage kids drinking, and I wouldn't know about it," said Lt. Phil Brust, of the San Diego County Sheriff's Department.

The California Department of Alcohol Beverage Control said they are in the process of completing a parallel investigation -- one that will determine where the alcohol came from -- to the California Highway Patrol's probe.

If the investigation reveals the homeowner had knowledge of what was going on, authorities said he could face civil or criminal litigation.

The investigation is expected to take several weeks.
