United States v Jeremy Esteves and Robert Brumfield

TrueAllele finds armed robber’s DNA on bandana

Crime On December 18, 2013, robbers ambushed an armored truck outside a Chase New Orleans bank. They shot bank guard Hector Trochez as he walked into the bank. Trochez died at the scene, and the gang fled with $265,000 in cash.
Evidence A bandana was recovered.
DNA The Louisiana State Police crime lab developed DNA mixture data from the bandana.
Match Due to the limited nature of the DNA data profile, the lab was not able to fully interpret the mixture. So they contacted Cybergenetics for TrueAllele analysis of their DNA data.
TrueAllele The computer found that a match between the bandana and defendant Curtis Johnson, Jr. was 200 times more probable than coincidence. At that match strength, only 1 in 4,100 people would match as strongly.
Cybergenetics    On November 6, 2019, DNA analyst Jennifer Bracamontes testified before a federal court jury about the TrueAllele results.
Outcome On November 13, the federal court jury convicted defendant Jeremy Esteves of murder. They found defendant Robert Brumfield guilty of planning a robbery, but acquitted him of murder.
