The two purposely crashed into other cars while laughing. Then they saw retired Police Chief Andreas Probst, 64, cycling in a bike lane. He would be the second man they rammed that day. Another cyclist, 72, survived after being hit by the two sweet and tender hooligans.

Ayala lined up his car behind Probst and said to his friend, "Ready?"

"Yeah, yeah, yeah, yeah, hit his a**," Keys gleefully responded.

Moments later, Ayala plowed into Probst, who fell back onto the car. Pieces of the windshield shattered into the front seat. Probst rolled over the vehicle and crumpled to the ground.

"That n***a knocked out," Keys exclaimed after the brutal assault.

"Sh*t, we got get outta here," Ayala responded.

The two drove on, leaving Probst to die in the street, and proceeded to steal two more cars before their violent frenzy was over. You can watch the video here, but be warned that it's graphic.
