The Thomson Elementary student who brought cocaine to school and shared it with classmates who were sickened and briefly hospitalized is back with his mother. The boy had been in foster care since the incident last Thursday, but after a hearing Tuesday in D.C. Superior Court he was sent back home, the Associated Press reported. No word on what discipinary action the child might face at school.

DCPS originally said that this was the fifth drug-related incident at the elementary level this school year. But a closer look found just three on record:

On Sept. 8, 2010, a Shaed Education Campus teacher found a student with marijuana during the school day.

On Nov. 11, 2010, a parent at Noyes Education Campus reported that another student had given marijuana to her child.

On Jan. 10, 2011, an Emery Education Campus student was found with an unknown green pill.

Schools spokeswoman Safiya Simmons said that in each instance school security and D.C. police were alerted, and meetings with parents were held. She said privacy laws barred disclosure of any other information.
