ANTELOPE VALLEY : Probe Into Poisoning of Teacher Intensifies

Authorities interviewed about 70 students Monday as they stepped up the investigation into the poisoning of a Antelope Valley high school teacher who became violently ill after she took a drink from a Diet Pepsi can laced with toxic dry-eraser fluid.

“We’re interviewing any and all students . . . to determine who did this,” Littlerock High School Principal Jeffery E. Foster said.

No suspects were arrested Monday in connection with the Thursday incident, but Foster said a $200 reward offered to students last week for information leading to the arrest and successful prosecution of the culprit generated several solid leads. He declined to elaborate. “I am cautiously optimistic that we’re closing in,” Foster said. “We have several students we are centering our investigation around right now.”
