Stevens & Scholten Tour ICE Detention Facility

In December, Immigration and Customs Enforcement said a detainee, Nenko Gatnchev, was found dead in a cell in the detention facility. He was a 56 year old from Bulgaria and was arrested in Chicago.

ICE says his death was from natural causes. Representatives Stevens and Scholten are pushing for answers, as they say they haven't been given any further details about Gantchev's death.

"There are unanswered questions around Mr. Gantchev's death and his family and his loved ones and people who have been frankly impacted or touched by his life story. They deserve answers."

Both lawmakers say the death raised concerns about conditions. One of the four detainees they spoke to said they have been mistreated in the facility.
