Testes of DNA on gloves found two kilometers from the house, carried out on February 17, did not generate matches in CODIS, leading to the use of genetic genealogy for mixed samples at the residence, a technique that compares profiles with public banks to identify distant relatives.
Inquiries to gun stores began the following week, with agents showing lists of names to owners to trace the holster, while cooperation with Walmart aims to identify the backpack. Contatos with Mexican authorities occurred as a preventative measure, with no evidence of crossing, and Nancy’s pacemaker is monitored for possible signs.
