Yasser Lopez, Teen Impaled With Fishing Spear, Reunites With Astrid Cardoza, The Stranger Who Saved Him (VIDEO)

"I was almost dead in these waters," 16-year-old Yasser Lopez told NBC. If it wasn't for the quick thinking of a total stranger, Astrid Cardoza, he may have been.

Lopez broke down in tears when he was reunited with the good Samaritan that held his hand and told him not to remove the spear during the gruesome incident this past June in Miami.

If Lopez had removed the 3-foot fishing spear that impaled him in the forehead and protruded through the back of his skull, he would have likely died at the scene, doctors later said.

Cardoza, who was near the lake at the time of the accident, heard screams and rushed over to help. In the video, she returns to the scene and shows where she found the two teens.

Lopez and his 15-year-old friend were "playing with a spear-gun" when the gas-powered weapon accidentally discharged and shot Lopez in the head. His friend called 911, telling emergency services that “A spear gun just went through my friend’s head,” and Lopez was rushed to Jackson Memorial Hospital in Miami, still conscious.

According to the video, doctors say it was a series of miracles that led to Lopez's survival -- the first being Cardoza's help before paramedics arrived. Doctors delicately removed the spear during surgery, finding that the rod missed certain crucial brain structures.

Although Lopez still faces months of physical therapy to treat the partial paralysis on the left side of his body, he survived the freak accident, thanks to one stranger's help.

Back at the scene, Lopez reunited with the woman who saved his life. Since he was in a wheelchair, Cardoza bent down and enveloped him in a warm embrace.
