The Best American Crime Reporting 2009 - Jeffrey Toobin [132]
Target’s crime labs are situated on the first floor of a sprawling office complex in an industrial park twenty minutes north of downtown Minneapolis. I was given a tour of the labs by Rick Lautenbach, Target’s manager of forensic services. We entered through a series of password-protected doors—Lautenbach punched his personal code into a keypad. “We can’t just go into a closet at the back of a Target store and open a crime lab,” he explained. “We have to have a facility that measures up to the government’s standards for admissibility of evidence.”
I was taken to a large, windowless room at the end of the main hallway, where Target operates its latent-fingerprint lab—a facility for detecting and recording fingerprints that are not visible to the naked eye. The room contained a fuming chamber, which resembles a glass-fronted refrigerator. To check for prints, agents place any type of nonporous object—plastic CD cases, metal iPods—in the chamber. A drop of Superglue is put into the chamber in a small tin dish and heated; the heat releases fumes of the glue’s active ingredient, cyanoacrylate, which adheres to the moisture secreted by fingertips, creating a visible white print. The prints are then dye-stained with a fluorescent pigment and taken to a small adjoining room with black walls, ceiling, and floors, for photographing and scanning under lights of different wavelengths. “We don’t have connectivity to any database with people’s criminal history, because we’re private,” Lautenbach says, “but we can match events together to catch a criminal or criminal gang and we pass that along to law enforcement.” Lautenbach told me about a recent case of a man suspected of repeated thefts at Target stores in Arizona. He was captured on a security camera as he picked up several items and put them in a shopping cart. Apparently aware that he was under surveillance, the man abandoned his cart and left the store. Loss-prevention agents retrieved a tissue holder that the man had handled and sent it to the fingerprint lab for analysis. Meanwhile, the investigations team was looking into whether the man was selling stolen items on eBay; recent online sale postings matched his known thefts. The agents made a “controlled purchase” from the eBay seller—a box set of “The Sopranos” on DVD. Lab analysis revealed that the fingerprints on both the tissue holder and the “Sopranos” DVDs were the same. “We turned the fingerprints over to the Maricopa County attorney’s office,” said Lautenbach. The man was convicted of felony trafficking in stolen property and computer tampering.
Next to the fingerprint lab is the video-analysis laboratory, a small room stocked with desktop computers and video equipment. Two agents sat at a computer and compared security-camera recordings of after-hours “smash and grab” A.T.M. thefts at several Target stores in three states in the South. One video showed thieves backing a Jeep Cherokee through the locked glass entrance doors of a Target, shattering them, then hitching a chain to the A.T.M. and ripping the machine off its moorings as they gunned away. Another tape showed the same crime, involving an S.U.V., at a different location. Though the thieves were masked, and the vehicles were different (the license-plate numbers revealed that both were stolen), the thieves’ practiced movements and the precision of their actions suggested to the agents that they were the same crew. Lautenbach explained
