Good Samaritan Apprehends Suspect After Fatal Car Crash.

It's the dramatic moment a good Samaritan took down an alleged drunk driver trying to escape the scene of a horrific fatal crash he caused. Dylan Molina drove through a red light, slamming head-on into a family sedan that instantly killed off-duty police officer Alex Cervantes, officials said. Justin Gonzalez pinned Molina to the ground after he tried to flee the scene. Police say he consumed eight double-vodka red bull cocktails and 16 single shots. The suspect pleaded guilty to intoxication manslaughter./Sarour
