Danville

Danville, north of San Ramon in Contra Costa County, is both a setting in the East Area Rapist’s history and a landscape the book reads for clues: a quiet suburb shaped by rapid growth, crossed by an abandoned railway corridor, and connected to a December 1978 attack and its investigation. The contrast between domestic calm and the largely unnoticed spaces at the edges of neighborhoods gives the town particular weight. Years later, Danville also became the starting point of a prolonged investigation of Jim Walther, who was ultimately ruled out as the East Area Rapist.

From agricultural valley to suburb

Danville occupies a broad valley adjacent to Mount Diablo. The account traces the area’s transformation from Native American camps near the mountain to land acquired in 1854 by a man named Dan, and then to a farming community where fruit and wheat production persisted into the 1970s. Residential construction subsequently reshaped the town. Its population doubled by 1980, as people moved into a suburb that the narrative characterizes as one of the East Bay’s wealthier and more comfortable communities.

That growth formed part of a wider change in central Contra Costa County. The new residential landscape replaced the possibility of industrial development and altered the relationship between homes, transport, and open land. Paul Holes consulted aerial photographs while considering the neighborhood connected to the attack; he saw no major construction surge there during the period when the East Area Rapist was prowling its backyards. The victim’s house had been built in the mid-1960s. Danville’s appeal as a place to settle therefore sat alongside an existing built environment that investigators were trying to understand, rather than a neighborhood newly created during the crimes.

The town’s present-day reputation for homogeneity and status consciousness appears in the account as a later frame for its development, not as an explanation for the attack. Its historically rural character, newer residential growth, and carefully settled suburban identity help establish the ordinary setting against which the criminal investigation unfolded.

The abandoned railway corridor

The Southern Pacific Railroad once ran through the valley on a branch line linking San Ramon with points north of Concord. The line carried passengers in its earlier years and later freight, including pears, gravel, and sheep. As roads and automobile travel changed the economics of transport, freight moved increasingly by truck. The tracks became less busy, and the railroad finally closed the line in September 1978, nearly a century after its construction began.

Closure left a twenty-foot-wide strip of land whose future had not yet been decided. In Danville, the vacant right-of-way cut through residential areas as a shadow corridor behind tidily enclosed backyards. Its fences and boundaries did little to draw attention to the land. The passage’s quietness was not presented as inherently threatening; its significance lay in how easily an unused route could escape notice while remaining accessible between homes.

The former railway later became the Iron Horse Regional Trail, a forty-mile path for walkers, bikers, and horses through central Contra Costa County. In the book’s account, the change from freight line to public trail reveals how a single corridor can carry different meanings over time. During the attacks, the abandoned tracks were an overlooked route; in the investigation, the same ground became a place to retrace movement and examine where a scent trail ended.

The December 1978 attack and the search

The East Area Rapist returned to Contra Costa County after attacks elsewhere and struck in Danville on December 9, 1978. The book identifies this as his first of three attacks in the town and as the source of his most promising lead. The attack came after a period in which residents had begun to hope that the previous wave of violence might have passed. Three attacks in twenty-one days had made October especially alarming; as weeks went by without another incident, that immediate fear had begun to ease.

The investigation brought bloodhounds to the railroad tracks. Pita, handled by Judy Robb, picked up a scent and moved south along the path beside the rails. She stopped about half a mile from where the search had begun. Betsey and Eli, two other bloodhounds, were also used at the scene. Their handlers recognized that wind and small changes in conditions could affect scent, but agreed on the broader indications: the suspect had spent considerable time prowling in the area, entered the victim’s backyard over the north-side fence, and left across the southwest corner of the back fence. The dogs’ route continued south along the tracks, ending at a cross street where investigators believed he had entered a vehicle.

That route linked the residential edge of Danville to a corridor that had become easy to overlook after the railway closed. Paul Holes later showed the location on the Iron Horse Regional Trail, identifying a point near an electrical pole where the dogs had lost the scent and where the suspect was believed to have reached a vehicle. He also discussed homework pages found in the area. The three dogs’ indications supported the route south along the tracks, while the location where the trail ended was consistent with the kind of distance from a target at which the East Area Rapist was known to park before approaching. The route thus offered investigators not a complete account, but a set of geographically coherent clues.

A location in a wider pattern

Danville’s significance rests partly on the way its setting connects with patterns described across the East Area Rapist’s attacks. The reports suggested that he selected neighborhoods, watched residents, and examined houses before an attack; signs could include prowling, unlawful entry, missing small items, and increased hang-up calls within a few blocks. In this broader pattern, the neighborhood itself—not only an eventual victim—became the object of reconnaissance. The abandoned right-of-way and the backs of residential lots give that pattern a concrete geography in Danville, without proving that every feature of the town played a part in the crime.

The book also emphasizes how residents’ responses shifted as the attacks became known. Early on, people had little awareness of a serial offender. Later, stories circulating in the community shaped what victims expected and how neighbors interpreted suspicious activity. Some residents, frightened by what they had heard, shut themselves away rather than intervene or call the police. Danville’s quiet residential setting therefore sits within a larger account of fear, vigilance, and the difficulty of knowing when an ambiguous sign demands action.

Jim Walther and the false lead

On February 2, 1979, Danville became the scene of another consequential episode in the case. Deputy Carl Fabbri found Jim Walther asleep in a gray-primer-coated 1968 Pontiac LeMans on Camino Tassajara, about a mile and a half from Interstate 680. Walther said he had pulled over to sleep after leaving work as a brakeman. Fabbri was patrolling after a failed attempt to chase a prowler the previous night, and the car’s location, together with the recent attacks, prompted him to investigate. Walther was twenty-one and had an outstanding warrant for vehicle-code violations; his record included a minor marijuana arrest in Sacramento. He was taken into custody, and his unusually strong reaction when officers tried to photograph him further fixed the encounter in the investigation’s memory.

More than thirty years later, Paul Holes returned to the exact place where Walther had been found. Holes spent eighteen months investigating him, and the search eventually established that Walther was not the East Area Rapist. Holes nevertheless described him as the offender’s shadow: an enduring suspect-shaped presence whose suspicious circumstances and long disappearance had drawn investigators into a separate mystery. Danville consequently holds two distinct investigative meanings. The December attack produced a trail along the tracks and a promising lead; the roadside encounter became an important false lead. Together, these episodes make the town a place where the geography of the crimes and the uncertainty of interpreting evidence meet.
