Police quickly discovered the address on Ward's driving licence was false. She was then asked how she intended to travel to Ireland with very little money in her possession. In response, she claimed to have intended to telephone friend in Ireland who would send her the money. The same evening, with Ward's consent, forensic scientist Dr. Frank Skuse obtained swab samples from her hands and fingernails to conduct Griess tests. These tests revealed what Skuse described as "faint traces" of nitrites upon one of her nails. A subsequent forensic examination by Dr Skuse of a caravan in which Ward had recently lived prior to her arrest also revealed what he concluded to be traces nitroglycerin upon a duffel bag and other personal possessions.
