NASHVILLE, Tenn. (WKRN) — The Nashville man found guilty of vandalizing the new Davidson County Downtown Detention Center (DDC) while it was under construction has been sentenced to 40 years in prison.

The self-proclaimed “criminal advocate” Alex Friedmann executed an elaborate scheme to hide away various weapons and accessories in the jail in 2019.

Surveillance video showed him concealing tools, drilling into walls, and hiding weapons. Guns, ammo, handcuff keys, and hacksaw blades were found inside the walls.

He was arrested in January 2020.

More than two years later, he was convicted by a jury in July. His bond was revoked.

He recently agreed to settle with state prison officials over the use of solitary confinement for pre-trial detainment.

He has also been found guilty of federal weapon charges. That sentencing is scheduled for Jan. 4, 2023. 

Friedmann has had prior convictions including armed robbery, assault with intent to commit first degree murder and attempted aggravated robbery.
