Investigators were called to The Arbors at East Cobb complex late Wednesday when another juvenile reported his girlfriend missing, police said Friday.
“He stated he tried to find her but was unable and that she had been missing for approximately two hours before he called 911 for help,” Marietta police said in an emailed statement.
Thursday morning, investigators located Segura, who told police he stabbed the girl as part of his initiation into the MS-13 street gang.
“According to the accused, the victim was (a member of the) 18th Street gang, which is a rival of MS-13,” his warrant states.
