Deputies responded to a complaint at about 2:40 a.m. Sunday regarding a loud party in a house on Linda Vista Drive that was believed to be vacant. "It sounded like there were about a hundred kids back there partying," said neighbor Phil Rado, who called 9-1-1 when he heard all the commotion early Sunday morning. Rado, who lives next door, said he was surprised to learn that the party began after the Helix Charter High School prom, which was held at the Hotel del Coronado. About 40 teens went to the post-prom party at the San Marcos house. When deputies went to the home, they found beer on a kitchen counter as well as hard liquor and mixers. "This is hosting a party where juveniles are attending in mass, and they're coming there for the sole purpose of drinking," said San Diego Sheriff's Lt. Jeff Maxin, who is with the sheriff's substation in San Marcos. The person charged with hosting the party is 24-year-old Jerome Spruille, who had rented the house to throw a party for his younger brother and about 40 friends after the prom. Deputies said Spruille admitted that he had served alcohol illegally to the teens. Spruille was arrested, cited and released. He could be fined $1,000 for a first offense. A second offense could mean double that fine as well as up to six months in jail. There is also potential liability in case anyone was hurt as a result. 10News went to Spruille's home but was told by his mother that he was not available for comment. Rado told 10News this was not the first time there have been parties thrown at the house, which is owned by Craig Miller. "He rented it out for weddings, just on weekends for people coming in from out of town," said Rado. "We had a big problem and the county told him to cease and desist because it was illegal and quite frankly, I'm quite surprised that he did it again. I think this is actually going to come back to bite him in the butt." 10News went online and saw the website for C. Miller Properties was down, but not a listing on theweddingchannel.com or a review found on yelp.com. Maxin confirmed the property had been rented through a website. When asked whether Miller could face charges of violating the social host ordinance, he told 10News that homeowners are responsible for things that occur on their property. "Ignorance is no excuse," he said. Miller has not been charged in connection with the party or for running a rental business in a residential area.
