The San Diego Union-Tribune reports that investigators are hoping to find a suspect in a cold case dating from 1967. This week marked 51 years since Nikki Benedict, 14, was fatally stabbed in the heart as she walked home in Poway. Her sister, who was just 5 at the time, is still haunted by the murder and the fact there have been no suspects arrested in the case.

Investigators are keeping much of the evidence under wraps, hoping to find a break in the case. They have stated that most of the evidence has been processed as normal, and no workable leads have been obtained from those processes thus far.

Nikki’s sister recently appeared at a news conference in the hopes of generating new leads in the case.

Police have stated that DNA can’t solve the case at this time, but they need new leads and any information the public may have about the unknown suspect.

In 1967, Nikki’s father told the media that she usually took the bus home, but had visited a friend on the day she was killed before walking home. She was wearing a plaid dress and headed down a hill to a stream bed when she was attacked. Evidence of a struggle was found at the scene. After being attacked, she managed to drag herself to the intersection of Poway and Carriage roads.

An 11-year-old boy found her at 6:30 p.m. while riding his bike home from Little League practice. She was bleeding, and the boy went to the market his father owned to get help. First responders tried to save her, but she was pronounced dead upon arrival at the hospital.

Some witnesses have said they spotted a young man running from the scene that day.

Many theories have been formulated over the years, one of which is that the Zodiac killer could be responsible.
