Doctor cycling on Pacific Coast Highway is mowed down by Lexus then stabbed to death by the driver

A doctor cycling on an Orange County highway was hit by a Lexus and then fatally stabbed by the driver, who was then restrained by shocked bystanders.

The cyclist, later identified as Michael Mammone, 58, was hit from behind by a white Lexus while riding on the Pacific Coast Highway in the Dana Point area on Wednesday.

After the crash, the Lexus driver exited his car and stabbed the cyclist in the back in front of horrified bystanders, leaving him lying on the highway with severe injuries.

Witnesses said the suspect struck was holding a BB gun as he approached the cyclist and then stabbed him at least once in the back.

The Orange County Fire Authority responded to a call of a cyclist being hit by a car near Crown Valley Parkway and East Pacific Coast Highway at around 3 p.m.

Mammone was then taken to the hospital, where he died. 

The suspect, later identified by authorities as Vanroy Evan Smith, 39, of Long Beach, was detained by bystanders and then taken into custody where he was booked on suspicion of murder. 

Footage showed Mammone’s mangled mountain bike and the shattered windshield and damaged front of the car. 

A knife, believed to be the one from the attack, was recovered at the scene. The sheriff’s office has not yet revealed if a gun was also recovered.

Officials said there appears to be no link between the victim and the suspect.

Mammone had been working as an ER doctor at Providence Mission Hospital Laguna Beach since 2011.

The hospital said in a statement: ‘We are stunned by this devastating tragedy. The entire Mission Hospital family is grieving over the loss of an incredible physician and friend. We will honor Dr. Mammone’s dedication to our community and passion for medicine by continuing to provide exceptional care.’

Mission staff said he was an ‘amazing doctor’.

Mammome would frequently ride his bike to work, as he lived a few blocks away.

The incident took place less than a mile away from the hospital.

‘That’s the irony of this whole thing. If a patient was brought in his condition, he would have done everything he could to save that person. He has saved so many lives here, and he died very close to where he saved hundreds of lives,’ said cardiologist Doctor Dawn Aatwal.

The Orange County DA’s Office said they are currently prosecuting close to 70 cases of vehicular death, with quite a few involving road rage, which seems to have risen since Covid restrictions were lifted and people returned to driving.

Other cyclists using the same stretch of Pacific Coast Highway agreed that drivers seem less patient and angrier, Fox LA reports. They said the crash occurred on a narrow part of Pacific Coast Highway, with little room for bicycles and cars, adding that quite a few people have stopped cycling in the area.
