Robert Brown|Pregnant Georgia teen's ex-boyfriend charged with murder in connection to her death

The Robert Brownex-boyfriend of a pregnant Georgia teenager found slain by family in a wooded area last week now stands accused in her death, police say.

Jesus Monroy, 17, is charged with malice murder, felony murder, feticide, and aggravated assault in the killing of 16-year-old Mia Campos, the Gwinnett County Police Department reported Tuesday.

Relatives found the teen dead the morning of July 15 in Loganville, a city about 35 miles east of Atlanta.

According to court records, Monroy is from Snellville, a city about 7 miles east of where Campos' body was found.

The department originally arrested Monroy on a charge of making false statements to police in connection to the case on July 17, two days after the girl's body was found.

Court records show Monroy is represented by Attorney Brandon Delfunt. USA TODAY has reached out to the court-appointed lawyer.
