A missing pregnant Georgia teen was found dead on Monday, prompting her boyfriend’s arrest two days later.

Mia Campos’ family reportedly tracked her cellphone to discover her body less than a mile from her Gwinnett County home. Campos, 16, left home with an unknown person a day before her body was located, according to WANF.

Campos was due to give birth in September. Her death was ruled a homicide.

“I found my daughter laid face down,” Campos’ father told WANF.  “I knew it was something wrong – her lips, her bleeding nose. They murdered my baby.”

Campos’ ex-boyfriend, Jesus Monroy, 20, has been charged with lying to police. He remains jailed without bond.

WXIA reported that authorities are still determining how Campos died. Additional charges may follow.
