SACHSE (CBSDFW.COM) - Two Wylie ISD schools received envelopes filled with a white powder Monday.
The first letter was discovered at Wylie High School late in the morning. Police and fire crews responded, but they were able to isolate the envelope in an office and did not have to evacuate the school.
Hazardous materials technicians investigated, and the powder was found to be cornstarch.
The envelope at the second school, Don Whitt Elementary, was found during the afternoon near the end of the school day.
Whitt is a Wylie school located in the city of Sachse.
According to Sachse city spokesman Ian Halprin, a hazmat crew is also investigating the second envelope.
At the time of this writing, the contents of the second envelope have not been identified. Investigators have identified the white powder as cornstarch.
Whitt Elementary was not evacuated and parents are being allowed to pick up their children.
Halprin says police are searching for any possible connection between the two envelopes.
