A Third Elementary School Received Suspicious Envelope.
A third Houston elementary school received a suspicious envelope containing white powder on Thursday.

The Bellaire police and fire departments, and postal inspectors were called out to Condit Elementary about 1:30 p.m. Investigators said school employees or students did not open envelope.

On Wednesday, Barbara Bush and Crockett elementary schools received similar envelopes, although firefighters determined that the power was not dangerous..

Over the past two days in Dallas, similar packages showed up at six schools, a church day care and a hospital. FBI agents are working to determine if the Dallas and Houston cases may be connected.
