New video shows moment of impact in Hialeah crash that killed three people – NBC 6 South Florida

Prosecutors revealed a key piece of evidence in the case against a 15-year-old accused of ramming his family's SUV into another car in Hialeah in April – surveillance video showing the moment of impact.

The only surviving woman died just this week, bringing the death toll to three.

Video captured the moment police said 15-year-old Maykoll Santiesteban, who was speeding while out joyriding with friends, crashed into a sedan.

Surveillance videos throughout the neighborhood showed the SUV speeding past. Police said Santiesteban was driving over 80 mph in a 30 mph zone.

“We have video surveillance from a nearby home camera that allows us to see the victim's vehicle come to a complete stop at the intersection, just as she was supposed to, but no one can expect a car as far away as that of the defendant.” “The case is coming at them at speed,” prosecutor Laura Adams said at a court hearing for the suspect earlier this year.

Yarina Garcia, 39, and Gloria Hernandez, 71, were killed that day. Liliana Hernandez Molina, 66, died this week after spending the past five months fighting for her life.

“From five seconds to two seconds before impact, the defendant was driving at a speed of 72 miles per hour, then 75, then 79, then 83 miles per hour,” Adams said.

Prosecutors said if the teenager had been driving at the 30 mph speed limit, he would have missed the family, who were driving just 9 mph, by about 100 feet.

“The suffering will last forever, but what we have now is enormous,” Hernandez Molina's husband, Bob Garcia, told NBC6 on Tuesday. The two were married for 43 years.

Santiesteban was charged with vehicular manslaughter and faces additional charges since the third victim died.

His lawyer said they were examining all the evidence and would plead not guilty.
