When it comes to criminals, a seven-year-old mild-mannered black Labrador Retriever named "Jax" might just be the most dangerous dog in Detroit.
Just ask 29-year-old Travis Wilson.
Wilson was recently convicted of Second Degree Murder in the shooting death of 20-year-old Cedric Smith Jr.
"I never knew a dog could do that," said Smith's mother, Umeka Ligon, who watched Jax in court as his handler, ATF Special Agent Jason Salerno, testified about the evidence Jax found that linked Wilson to the killing, including two particles of gun powder residue that Jax detected on Wilson's pants shortly after Detroit Police nabbed him.
But Jax didn't just get lucky. He's an ATF Certified Explosives Detection Canine and he has the ability to alert on over 19,000 explosives odors. Jax has even found the shell casing from a round fired a year earlier.
He's part of Salerno's family in Michigan, but works throughout the country. Right now, Jax and Salerno are assigned to assist Detroit Police Homicide investigators.
Travis Wilson will be sentenced on Friday.
