A New Jersey teacher faces disciplinary action for a Facebook post disparaging Mexicans stemming from the disappearance of 5-year-old Dulce Maria Alavez .

The comment allegedly written by Jennifer Hewitt Bishop blames Mexican culture for the girl's disappearance.

“They don't supervise their children like we do,” the comment read.

A monitor for South Jersey’s Vineland Public School District Facebook page spotted the comment, which has since been deleted, and notified superiors.

Dulce Maria vanished Sept. 16 from City Park in Bridgeton, New Jersey. Her mother was in a car nearby with another child as the missing girl played with her 3-year-old brother by the swings. The 3-year-old returned to the car alone. The mother searched the park before calling police. A statewide amber alert was issued.

Joseph Rossi, executive director of personnel for Vineland Public Schools, told NBC News he was told about the comment Friday and opened an investigation of Bishop, who has been suspended.

“Appropriate action was taken,” Rossi said. “An outcome will be reached after consultation with the Board of Education's personnel committee.”

The search for Dulce Maria is ongoing. Witnesses reported seeing her enter a red van with an unidentified man. New Jersey law enforcement agencies and private businesses are offering a $35,000 reward for information leading to the girl's whereabouts.
