After two months, the host's son decides the only way to get rid of this houseguest was to kill him: Cops hold son in slaying of houseguest Jaxon Van Derbeken, Chronicle Staff Writer Thursday, August 29, 2002 San Francisco -- An El Sobrante woman's offer to shelter a homeless man ended with her son allegedly bludgeoning the houseguest to death after he overstayed his welcome, San Francisco police said Wednesday. Rafael Chavez, 55, was killed in the East Bay, but San Francisco police got the case because his bound body was dumped in March on Sunrise Avenue near the Sunnydale public housing project. Police say Carlos Stewart, the 21-year-old suspect in the case, confessed when San Francisco police investigators went to a Bakersfield jail to interview him this week. Investigators also found evidence at the home in El Sobrante that pointed to Stewart, police said. Police said Chavez had been painting in El Sobrante last spring and one day went door to door in search of his lost dog. He met Stewart's mother, Sheila Bush, and told her he was homeless. Bush offered him a place to stay in her garage in exchange for house chores and painting, said San Francisco homicide Inspector Holly Pera. After living two months in the garage, Inspector Joe Toomey said, Chavez apparently had outstayed his welcome. Stewart, said Toomey, "didn't want him around." Stewart told investigators that Chavez had been high on drugs and had provoked a fight. "The suspect said he pushed him to the ground, but he got up, so he pushed him to the ground again," Pera said. "He denied hitting him with anything, but it does appear the victim was struck with something," Pera said. Stewart "tried to tell friends and family members that someone had broken in and killed him," Pera said. Pera said that Stewart had admitted to calling his brother and enlisting him to get rid of the body. The brother has not been arrested. E-mail Jaxon Van Derbeken at jvanderbeken@sfchronicle.com.
