Sarah Laird

Professor Sarah Laird (PROSE: Resurrection of the Daleks) was a scientist attached to the bomb disposal squad of the British Army in 1984.

Biography
While the rest of the soldiers in the squad were killed and replaced by Dalek duplicates, Laird helped Tegan Jovanka escape the warehouse where they were situated; however, Tegan ended up being recaptured by Lytton's "policemen".

Laird panicked and ran when the duplicate of Colonel Archer ordered his troops to put her and Tegan into the time corridor, whereupon she was shot and killed by the duplicate soldiers. (TV: Resurrection of the Daleks)
