SAN JOSE -- A teen boy is in police custody and another is being sought in the home-invasion robbery of an elderly couple during which they sexually assaulted an 85-year-old woman, then stole their car and tore through the city at breakneck speeds before crashing into a home across town, authorities said.
San Jose police said the sexual-assault victim was taken to the hospital and is expected to survive. The home that the suspects crashed into was vacant.
The frightening episode began around 4 a.m. Tuesday when the teen suspects -- armed with "sharp instruments" -- broke into the rear of the well-kept, two-story home in the 1500 block of Sunshadow Lane, near East Capitol Expressway and Story Road.
"Two suspects entered their home armed with weapons. They were forced to the back of the house," police spokesman Officer Albert Morales said. "At some point, the 85-year-old female was sexually assaulted."
Police declined to give additional details about the attack. The male resident, also 85, was not injured.
The suspects then stole the couple's Chevrolet Equinox SUV and were soon spotted weaving across all lanes of southbound Highway 101 near Tully Road, said Officer Ross Lee of the California Highway Patrol.
CHP officers followed the speeding vehicle as it exited at the next offramp at Capitol Expressway then turned south onto Senter Road, Lee said. When the driver of the SUV tried to take a hard turn at Singleton Road, he lost control and crashed into the garage of a vacant home near Andrew Hill High School.
The driver got out of the wrecked vehicle, ignored officers' commands, and ran off, hopping a fence in his escape, authorities said. The passenger, a 15-year-old boy, was still pinned in the SUV, and was arrested, interrogated and booked into juvenile hall.
It was only after the crash that investigators discovered the SUV had been stolen and traced it back to the site of the home invasion, police said.
Police say they discovered graffiti on a shed in the backyard of the couple's home on Sunshadow Lane but did not know if the markings were left by the suspects. Police did not immediately say if the graffiti was gang markings.
Tuesday morning police were searching for the driver, who they described only as a male suspect between the ages of 17 and 25 with possibly a severe laceration on his body.
