there she was, friday, the 26th, captured on supermarket security video casually shopping. that night, derrick said, the two watched a movie on their entertainment system that had just been repaired. kim used to call it nasa. because i would always have to change the input for her, change the channel or get it to the place that she wanted to watch. reporter: so many people can relate to that. too many remotes. reporter: you had just had a sound person correct. reporter: come in and help you out? i was trying to have him simplify it. take those five remotes on the table and turn it into one. reporter: the next day, saturday, the 27th, derrick left his wife sleeping and headed to his fire station to begin a 24-hour shift. it coincided with a big college football game, florida versus georgia. it s a large influx of people into into the city. and of course, with the football game comes drinking and foolishness. reporter: what kind of calls

it checked out. josh was just up on the north side of jacksonville. nowhere near the dorsey home as far as they could tell. kim s husband derrick, likewise, had a solid alibi. but detectives still weren t sure what to make of him. they knew he was an unfaithful husband, which gave him a possible motive. at this point, were you able to rule out derrick dorsey? absolutely not. i mean, you know, he could have definitely had someone setting this up. then again, if he had hired someone to kill kim, why was he acting so darn helpful? derrick s calling me daily, and obviously there are times i had to call him, you know, to get some information about things at the house, you know. and so, yeah, he s cooperating. he s doing everything, you know, that i m asking of him. finally officers and technicians were done processing the crime scene and derrick could return to the house. so the night we go to turn the house back over, i think it was halloween, the 31st.
