Video: K-9 alerted by smell from suspected WHCD shooter
A security K-9 detected a scent from Cole Allen, the suspect in last Saturday's shooting near the White House Correspondents' Dinner, before he attempted to run past a security checkpoint. The dog's handler pulled the dog back just before Allen darted into the hallway and ran past the checkpoint while armed.
A newly released video shows Cole Allen, the suspect in last Saturday's shooting near the White House Correspondents' Dinner, being followed by a security K-9 moments before he attempted to run past a security checkpoint. The K-9 detected a scent as Allen entered a stairwell. Michael Gould, a founding member of the NYPD K-9 Unit, believes the dog alerted to the odor of explosive materials. The dog was likely a vapor-trailing dog, trained to follow scent particles emitted by a person. Gould stated that the K-9 operation demonstrated the effectiveness of layered security, with the dog being a highly trained piece of technology that can detect otherwise odorless substances.
