A former roommate of the suspect in a failed bomb plot in Dallas says his friend was lonely and suicidal in recent months.

Joshua Childress told WFAA-TV that he was worried about 19-year-old Hosam Maher Husein Smadi, a Jordanian who lives in Italy, Texas.

Childress, who lived with Smadi last year, says the pair would talk for hours and Smadi "wasn't happy" being away from his family.

Smadi was arrested Thursday after federal officials say he put what he thought was a bomb-filled truck in a garage beneath a Dallas skyscraper.

Smadi is being held on charges of trying to use a weapon of mass destruction. A judge on Friday appointed an Arabic translator and a lawyer for Smadi. His next court appearance is schedule for Oct. 5.
