He testified that at about 2:30 in the morning of the 27th, he was awakened by his brother Albert who was tapping on the window and wanted to borrow money from him for a night's lodging.

At the request of a member of the jury Collins also demonstrated the difference in a print caused by various levels of pressure. After Collins took the
