The sheath quickly became sensationalized in the document : The report expire that Tirrell , who treat Bickford as a quixotic partner , was green-eyed that she ’d taken another customer . After that customer depart Bickford ’s room , Tirrell allegedly took a razor to Bickford ’s neck and slit her throat and then lit multiple fire to destroy the grounds . Perhaps most incriminatingly of all , Tirrell fled to New Orleans before he was finally arrested .
Once apprehended , Tirrell hired celebrated Boston attorneyRufus Choate , who had made a reputation for his groundbreaking , elaborated contorting of the law , which generally kept his clients out of the slammer . In this case , Choate argued that , because Tirrell lacked any real motif to down Bickford out of dusty blood and there were no eyewitnesses to the real crime , proof beyond a fairish doubt would be out of the question to attain .
If it were the case Tirrell kill Bickford , Choate reason , could it not be the fount that Tirrell , who sleepwalked occasionally , could have been sleepwalk when he committed the act ? The jury apparently bought it : It only took the jury two 60 minutes to find Tirrell not guilty . Choate had successfully make the “ insanity of sleep ” defense .
