The murder of a 14-year-old girl in her Castro Valley home in 1994 that rocked the Bay Area has gone unsolved for the last 28 years, and a reward fund for information leading to the arrest and conviction of her killer is now being increased, it was revealed late Thursday afternoon.

The reward is being increased from $100,000 to $200,000, said John Lin, whose daughter, Jenny, was found stabbed to death in her home in Castro Valley between the hours of 5:15 p.m. and 6:45 p.m. on May 27, 1994. Jenny was an eighth-grade student at the time of her killing. There was no apparent reason for her murder nor a motive, and the killer remains at large.

Lin said his daughter was a well-liked, straight-A student. The $100,000 reward was established shortly after her murder.

To continue their commitment to solving the case, Jenny's family and friends have increased the reward amount to $200,000.
