The holiday weekend in San Marino, California, had a tragic start when an innocent man and his dog were killed as a result of needlessly reckless driving.

Two minors were racing their cars at high speeds down city streets when one crashed, causing a tragic accident.

A white Mercedes cut across all lanes of traffic during the dangerous race when the driver lost control of the vehicle. The car skidded and spun and finally came to a stop…but not before striking a man and his dog that were jogging along the median.

Both the man and his four-legged best friend died on impact, according to Police Chief John Incontro. The man was thrown approximately 30 feet from the collision and his dog was thrown at least 60 feet.

The victim of the sad accident wasn’t alone, either. He was running with a woman who was just behind him, but luckily she was far enough away to avoid being struck herself.

The boys operating the vehicles were both underage and are now in custody. They may not realize it now, but their selfish acts have forever changed the course of countless lives.

All pedestrians must be cautious when walking along any kind of motor way, but tragic accidents like this would be hard to prevent completely. Always make sure to wear reflective gear (and to put some on your furry best friend).

You never know what small thing might be the difference between life and death.
