2 mins read

Two people have been arrested in connection to the shooting and killing of an employee at a Pleasanton Home Depot. The victims are accused of murder, robbery, child endangerment, and conspiracy. 

The victim was identified as Blake Mohs, 26, from Tri-Valley, and is working as a loss prevention employee at the store. According to police, he is well-known within law enforcement as the reporting party of any store incidents. 

“I am devastated by the loss of Blake Mohs in yesterday’s senseless shooting. Through his service to Tri-Valley organizations, Blake was a model for others. To have a life cut short is heartbreaking and infuriating. I’m joined by the City Council in offering our deepest condolences to Blake’s family, friends, loved ones, and to everyone impacted by this tragedy,” said Mayor Karla Brown.

Police were dispatched to the Home Depot at 6000 Johnson Drive at around 2:15 p.m. Tuesday. They found one victim bleeding inside the store. 

Police said suspect Benicia Knapps was trying to steal an electrical item from the store and was confronted by Mohs. 

Knapps pulled out a handgun and shot Mohs, killing him. 

According to police, Knapps ran to a getaway car driven by Guillroy and that there was a 2-year-old child inside the vehicle. After getting away, police found an unregistered handgun at a nearby intersection. 

The Alameda County Sheriff’s Office was able to track the suspect vehicle to a residential neighborhood in Oakland. 

Knapps, 32, and David Guillroy, 31, were arrested in the 7000 block of Ney Avenue. 

Guillroy was arrested and booked into the Santa Rita Jail in Alameda County. Knapps is currently receiving medical treatment from the incident, not the arrest, police said. 

They face charges including murder, robbery, child endangerment, and conspiracy, according to officials.
