Overview
- Authorities say DNA from a glove found about two miles from the Tucson home produced no hit in CODIS and did not match DNA recovered at the residence.
- Investigators report additional biological evidence from inside the home is under lab analysis, and they may pursue investigative genetic genealogy to develop leads.
- Sheriff Chris Nanos says the suspect likely had a specific target, and teams are scrutinizing a distinctive gun holster and a possible ring visible beneath a glove in surveillance images.
- The backpack seen on the suspect was identified as an Ozark Trail model sold by Walmart, and investigators are working with the retailer to trace recent purchases.
- Efforts to retrieve more Nest camera footage face technical hurdles despite assistance from Google and other companies; the family has been publicly cleared, a $100,000 FBI reward stands, and no arrests or proof of life have been announced.
