Your DNA statistics are wrong. In DNA match of 1 in 1 million probability means that the particular DNA profile is present in 1 out of every 1000 people in the general population, not one in every million. In DNA the probability is the probability that the suspect, the sample, and a random person from the population will all three have the same DNA profile. To find the DNA odds you think they are saying, take the square root of the DNA expert's probability. So, for your example, a one in a million match means that there are about 65,000 people in the population with that DNA profile.
