Another suspect is arrested in connection to the kidnapping of a 15-year-old girl.

Officials tell us the minor was sold to two men, for sex.

A total of four people are now behind bars in connection to this case, which is still open, as two more remain at large.

19-year-old Elizabeth Cantu was brought before a judge today. She’s charged with engaging in organized criminal activity and trafficking a child; her bond is set at $1.2 million.

Cantu joins 17-year-old Briseyda Flores and 22-year-old Juan Manuel Valdez who were arraigned earlier in connection to the case.

“They all, working together, helped to facilitate the sale of this 15-year-old victim to the two primary suspects,” says Sergeant JP Rodriguez, of the Hidalgo County Sheriff’s Office.

Those suspects are 36-year-old Ricardo Mata and 37-year-old Erick Martinez Lopez, who authorities tell us, bought the girl for $300. Mata and Lopez then contacted the girl’s mother, demanding a $1,500 ransom.

“As they were demanding money from the mother, the mother reported this to Zapata County,” says JP Rodriguez. “Who then notified us in the early morning hours, and we were then able to rescue her from that home in mission last week.”

Mata was arrested at the home, on Ramona Boulevard; his bond set at $1 million. His accomplice, Erick Martinez Lopez remains on the run tonight.

“We have a warrant for his arrest for aggravated kidnapping,” says JP Rodriguez.

The other suspect authorities are searching for is a man connected to Elizabeth Cantu. Apparently he helped Cantu arrange the sale of the 15-year-old girl.
