In late January 2009, coworkers of Alan Henry Lindley grew concerned when he unexpectedly failed to show up for his job. Lindley, a 60-year-old white man who resided in Claremont, California, was not someone accustomed to missing work without explanation. When his continued absence stretched over several days and attempts to reach him proved unsuccessful, his employer contacted local law enforcement and requested a welfare check on his residence.
Officers from the Claremont Police Department were dispatched to Lindley's home, situated in the 700 block of West Arrow Highway. Arrow Highway serves as a prominent east-west thoroughfare linking Claremont to neighboring communities across the eastern Pomona Valley, bordered by suburban residences, trees, and nearby commercial corridors. Under normal circumstances, the tranquil, tree-lined college town experiences very little violent crime, making an emergency check on an unresponsive resident an uncommon and urgent matter for responding officers.
Upon arrival at the home, officers entered the residence to conduct a walkthrough of the interior. Inside, they made the grim discovery of Lindley's body. He was found deceased, having suffered severe physical trauma. Authorities determined that his death was the result of a violent attack, noting multiple sharp force injuries and puncture wounds concentrated across his chest and lower abdomen. The Los Angeles County Department of Medical Examiner-Coroner evaluated the scene and officially classified the death as a homicide, listing his date of death as January 30, 2009.
Detectives with the Claremont Police Department secured the house and initiated an intensive crime scene investigation. Investigators combed through the residence for forensic evidence, searching for signs of forced entry, potential weapons, stolen property, and biological traces left behind by the perpetrator. Because Lindley had not been heard from over a span of days, detectives determined the homicide had occurred sometime between January 28 and January 30, 2009. Despite their inquiries into his routine and recent interactions, no immediate suspect was identified at the scene.
In the months and years following the murder, investigators pursued potential leads, seeking to uncover a motive behind the fatal stabbing inside his own home. The brutality of the wounds suggested a close-contact and violent encounter, yet investigators found no clear indication of who would have targeted him. Claremont typically registers long periods with zero homicides, and violent crimes of this nature are exceedingly rare in the city, making the lack of answers particularly difficult for the community and those who knew him.
Today, the murder of Alan Henry Lindley remains classified as an open cold case. More than a decade and a half after the crime occurred, no arrests have been made and no suspects or persons of interest have been publicly named. The Claremont Police Department keeps the case featured on its roster of unsolved homicides, maintaining that individuals in the community may hold vital information regarding who was responsible. Anyone with knowledge about the homicide is urged to contact the Claremont Police Department Detective Bureau or submit an anonymous tip through Los Angeles Regional Crime Stoppers.
