>> a month. >> now to describe his state in the days before the murder. >> did you at some point receive a phone call from your son? >> yes. >> she described the conversation with her son, two days before the murder. he was inconsolable over the breakup with beth. >> he said, she's gone, she's gone, she's taken all of her stuff. i was asleep and she just left. >> the next day, sunday, the toolan went to manhattan to see their son, he was in terrible shape. >> his whole body exuded, you know, the smell of alcohol. >> the defense believed that establish toolan's state in the days before the murder. now, for the day itself. when he was picked up in rhode island after the murder, he had been drinking. sobriety test later put him at twice the legal limit. >> multiply that by six -- a >> forensic toxicologist doing some complicated calculations estimated that at the time of the murder toolan's blood alcohol level was 0.300. >> where does that fit? in >> that fits in the next level above confusion to the stupor phase. >> the defense argued, tool and was profoundly impaired at the time of the murder, and that was just from the drinking, add in the drugs, how much did drugs play in tom toolan's life? >> he will take whatever drugs he could take -- >> such? as >> methamphetamines, zoloft -- >> there was more the defense revealed that toolan had spent years fighting depression and ocd, in the left 80s he had attempted suicide. finally the defense was ready for its knockout punch. >> i would call doctor donald. >> a neuropsychologist. >> my opinion is that he has profound frontal executive dysfunction. >> he testified that years of substance a bruise had bought about that mental defect. because of it toolan could not control his impulses and the defense argued that he could not be held criminally responsible for the murder. >> it's like the perfect storm. you have the frontal lobe defect, a person is unable to control their emotions and the executive function, coupled with the lowering of the inhibitions through the alcohol, you have all of these swirling together inside this man's head. >> the prosecutor's job was to blow that argument away, to argue that tom toolan knew exactly what he's doing when he murdered beth lochtefeld. that he was so enraged by the breakup that he planned and carried out a cold, calculated killing. >> we're presenting to your timeline -- >> as evidence of premeditation prosecutor told the court that on the night before the murder, security guards at new york's laguardia airport stop toolan from boarding a plane to nantucket because he was carrying a ten inch knife. when asked about the knife, toolan offered a series of stories. >> he said that he had forgotten that it was in their. >> he had to cut a birthday cake. >> he was having lunch with his sister in nantucket and she wanted him to bring a knife. >> the prosecutor presented evidence to show that the next morning toolan boarded another plane bound for nantucket this time without a knife. but when he landed, he went shopping for knives. toolan may have been drinking that day, the prosecutor argued, but he was used to consuming quantities of alcohol and drug without showing it. the prosecutor called witnesses who would testify that toolan didn't seem drunk. >> raise your right hand please. >> that's what's the clerk who told him the knife said. >> i would say he was sober. >> and the rental car ancient at the nantucket airport. >> did he seem intoxicated to at that point? >> no. >> food you have told him to carve he appeared intoxicated to you. >> not likely. >> they played a surveillance tape from the airport at massachusetts, tulane flew in to the airport after the murder arriving at around 1:15. jurors can see him renting a car, walking up to get it and driving away in a gray chevrolet impala. >> you're able to see how he's walking, and he's not falling, he's not stumbling. the persons are interacting with him, and they're interacting in a normal way. >> and there was audio of toolan in the back of the state trooper cruisers after he was arrested in rhode island. >> can you tell me what's going on, officer? >> i said will discuss it when we get back to the barracks. >> the prosecutor argued toolan was coherent. he was capable of thinking clearly and of distinguishing right from wrong despite the alcohol. and the prosecution also had a forensic psychiatrist whom they thought would deliver their own knockout punch. >> were you able to form an opinion concerning the criminal responsibility of thomas toolan the third on october 25th of 2004 in respect to the killing of beth lochtefeld? >> on that day, he did not have a mental disease or defect. >> and so, the prosecutor told the jury, tom toolan was criminally responsible when he stabbed beth lochtefeld to death. the testimony took nine days in all. as the summer arrived on nantucket, the surf and see beguiling visitors, the stores beckoning shoppers, inside the nantucket superior court, the jury in toolan the's murder trial got the case. >> coming up. the end of a trial. >> is the defendant guilty or not?
