Overview
- A white forensic tent was set up Thursday morning over the front porch of Guthrie’s Tucson-area home, the spot where blood was previously observed and a masked person appeared on surveillance footage.
- Authorities have not said a body was found and have not confirmed new discoveries beyond the earlier blood evidence.
- Law enforcement experts say such tents protect fragile materials like trace DNA, fibers, and impressions and create a controlled workspace, with any lighting or environmental reconstructions remaining unconfirmed.
- The Pima County Sheriff’s Office is leading the investigation with support from Arizona Department of Public Safety specialists, and the FBI has not announced formal involvement.
- Residents have been asked to review security footage from Jan. 31 between 9:30 and 11 a.m. and from Jan. 11 between 9 p.m. and midnight to help refine the timeline.
