Veronica Buchman was the partner of Roger Buchman and the mother of Toasty Buchman. She was a technician. She helped to track Flip Jackson when the microlite she was using to get to the transmat station crashed.
She later rewired the house electrics, so she could use them to kill the Wirrn (AUDIO: Wirrn Isle)
