EL PASO COUNTY, Colo. - Two teens found dead Sunday near Pikes Peak International Raceway have been identified.
They are 15-year- old Derek Benjamin Greer and 16-year-old Natalie Partida, both students at Coronado High School.
A memorial is growing on Old Pueblo Road where the pair was found dead.
"I counted him as my brother but we weren't blood-related," John Kincaid said.
Kincaid grew up with Greer, and the two were best of friends.
"He was just awesome. He was just fun and really happy all the time," Kincaid said.
Kincaid said Greer was supposed to sleep over Saturday night, the night before he and Partida were found dead.
"It got to eight o'clock and I kept texting him and blowing up his phone, and he wouldn't answer me. He finally saw it, but he didn't respond," Kincaid said.
Kincaid said Greer and Partida were close.
"She always kept him happy," Kincaid said. "He loved her."
Over the past year and a half, Kincaid said Greer had started going to more parties.
"We just asked him 'Why would you go? You have us here, you don't need to go party to have fun,'" Kincaid said.
Unanswered questions remain about how their bodies ended up on Old Pueblo Road, and who killed them.
"We're investigating this as a double homicide," Jacqueline Kirby with El Paso County Sheriff's Office said. "We are aggressively, aggressively investigating this case."
Kincaid hopes whoever is responsible is caught soon.
"That was one of the best people I have ever known in my entire life, and I don't know what we're all going to do without him," Kincaid said.
His final words to his best friend plea for his return.
"I love you, come back," Kincaid said.
