Alex James Barnett, the Tucson murder suspect whom online sleuths have compared with the so-called 'Porch Guy' seen near Nancy Guthrie's home, was arrested after a three-hour SWAT standoff on the east side of the Arizona city on Monday night.
The Pima County Sheriff's Department said Barnett, 33, surrendered peacefully at an apartment complex near East Broadway and South Camino Seco.
