In 1994, the brutal murder of a 14-year-old inside her parents’ safe suburban house left a community shaken to its core, because not only had a bright and talented life been suddenly snuffed out, but police struggled to find a motive. And the more clues they uncovered, the more investigators realized the nightmare they were dealing with: Jenny Lin’s murder was more than a crime of opportunity — it had been carefully planned. For nearly 30 years, Jenny’s murder has weighed on Alameda County and terrorized detectives as they’ve pondered the same question over and over since 1994: why Jenny?

Footprints found at the Lins’ home. They appear to be boot prints — perhaps from Gorilla work boots or a similar brand. Investigators estimated the shoe was between a men’s size 9 and 11. Photo Courtesy: Alameda County Sherriff's Office
