something naughty. i just go in and go, i need to see this old report, please. i then get the crime lab report which tells me that the blood type is blood b. >> we were incredibly excited because we know now the perpetrator had type b blood. >> but we didn't know what john's blood type was. so what we did first, we called john. >> my blood type, i don't know. he said, you don't know your own blood type? no. you think your mom will know? i said, i don't know, call her and ask. >> i spoke to his mother, please tell me you know his blood type? no, i don't. so i'm wracking my brain. i asked john, did you ever have surgery at any time of your %-p your blood and test it. yes, when i was a teenager at charity hospital. thank goodness. again, scramble, scramble, go to my connection there who was the direct over the records' room. i said three weeks from now this man's going to be executed. it's a matter of life and death,
