Colin Rand Kaepernick was born on November 23, 1987, in Milwaukee, Wisconsin. He was just a few weeks old when he was adopted by Rick and Teresa Kaepernick, who already had two children of their own but had lost two other babies not long after birth because of heart defects.
Kaepernick's biological mother, Heidi Russo, was 19 when he was born. Faced with the prospect of raising her son on her own (Kaepernick's biological father fled as soon as he discovered Russo was pregnant), she had spent much of her pregnancy debating whether she should put her baby up for adoption. After meeting the Kaepernicks, who had been introduced to her through a common friend, she decided to give her young child up.
As white parents of a bi-racial child, the Kaepernicks often received stares or curious comments. At school, classmates told Colin that it was impossible for the Kaepernicks tobe his parents.
"We've always been really open about the adoption, and we were always very open about the skin colors," Teresa Kaepernick told
The New York Times in 2010. "We pointed it out as a positive, and he saw his difference and was comfortable with it."
Athletic at a young age, Kaepernick, who moved with his family to California when he was 4 years old, began playing youth football at age 8. His strong arm quickly elevated him to the quarterback position. That same arm also made him an elite high school pitcher, one capable of throwing a 94-mile-per-hour fastball.
But football was Kaepernick's first love. In the fourth grade, he even penned a letter predicting that he would be the starting quarterback for the San Francisco 49ers. "I hope I go to a good college in football then go to the pros and play on the Niners or the Packers, even if they aren't good in seven years," he wrote.
At John H. Pitman High School in Turlock, California, Kaepernick was a first-team All-District, All-Conference and All-Academic selection
. But Kaepernick, whose big arm was hampered by what scouts viewed as a poor throwing motion, was largely passed over by the major college football programs. There were also concerns that the razor thin athlete—he matched his 6'6" frame with just 170 pounds—would get hurt.
