jamie was taking time off from her studies at texas a&m and was working at a pizza parlor. her shift ended at midnight. we contacted everyone she delivered pizzas to and nothing out of the ordinary. afterward she headed to a friend s house. she watched movies and left the house at 11:30. what time do you think she was killed? we got the call at 7:15 a.m. so between 4:30 a.m. and 7:00 a.m. the friend was supposed to be the last one that saw her alive. the detective paid him a visit. he was upset, obviously. they were friends and had been for some time. the friend s grief seemed genuine, but something wasn t peculiar. when investigators asked for a dna sample he said no. no? of course, we wanted to know why. was he the killer or was he not? the detective was determined to answer that question.
