The Pleasanton police continue their investigation into a shooting homicide that took place last Friday. According to the Pleasanton Police Department's social media update, 28-year-old Lucas Chan has been arrested for the murder of his father, Lance Chan, age 61, after a reported dispute. In a chilling development, the law enforcement's search uncovered an array of ghost guns and the presence of explosive devices within the suspect's residence.

Tragedy struck the 4600 block of Helpert Court around 9:40 p.m., where, upon their arrival, responders discovered the victim suffering from a fatal gunshot wound. Despite police efforts, the victim succumbed to injuries at a local hospital and was later pronounced deceased. Lucas Chan, who was initially, though mistakenly, reported as 29 by the authorities, was apprehended at the scene and faces homicide charges, with his residence revealing more layers to the case, including suspicious devices that prompted involvement from the Alameda County Sheriff's Explosive Ordnance Disposal Team.

With the troubling elements of explosives entering the equation, the Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF) has since stepped into the picture, contributing their expertise in light of the found 3D printed firearms and explosives. Pleasanton Police assure the public there's no current threat to safety. However, the investigation's tendrils stretch as they pursue additional information and urge anyone with knowledge to step forward by calling (925) 931-5100.
