Abdullatif Aldosary (pictured), currently a resident of Coolidge Arizona, is being questioned about the bomb set off in the Casa Grande Social Security office Friday morning.

The police kept neighbors of Aldosary out of their homes for hours until they determined the residence was safe, so they may have suspected a bomb trap.

Aldosary served eight months in prison for aggravated harassment of his employer in Gilbert. He has a current case involving assault in Casa Grande. Why wasn’t he deported?

Iraqi refugees and immigrants have proved to be a particularly troublesome bunch, from daughter-murdering dad Faleh Almaleki to Kassim Alhimidi, who disguised the killing of his wife as an anti-Muslim hate crime. It was reported last year that Iraqis were inadequately vetted before being admitted to the US. Senator Rand Paul called for hearings on that topic after a couple of unexamined refugees, Waad Ramadan Alwan and Mohanad Shareef Hammadi, were arrested on terror charges in Kentucky. Alwan had supposedly fought against Americans in Iraq, but was nevertheless admitted as a refugee in this country.

Was Aldosary a predictable problem, particularly a known jihadist back in Iraq? Hopefully we will learn more soon.

A 47-year old Iraqi refugee is in federal custody Saturday in connection with an explosion at a Social Security office in Casa Grande.

A source close to the investigation says he’ll likely face a litany of federal and state explosive and arson charges on Monday. 

“I’m positive in my heart and my soul he had nothing to do with this,” said Swannee Welsh

Welsh believes her neighbor, Abdul Latif Aldosary is being unfairly targeted. She says he’s a refugee from Iraq.

“I’ve never seen him with a match even, he doesn’t drink, doesn’t smoke, he doesn’t move, he doesn’t go to the mosque,” said Welsh.

But Saturday, federal agents were still searching Aldosary’s home at 47th Street and Lemon in Coolidge.

The 47-year old is being held in connection with an explosion at the Social Security office in Casa Grande Friday morning.

Investigators believe someone threw an explosive out a car window, causing the entry door to become blackened and charred.

The office was closed and no one was hurt but the blast shook those nearby.

“He was just in that neighborhood because he goes to unemployment offices and other government buildings over there but he hasn’t any problems against America; he’s very thankful he got to be a refuge somewhere,” said Welsh.

Friday evening, dozens of homes near where Aldosary lives were evacuated as a precaution as agents served a search warrant.

“It’s kind of a surprise, wouldn’t expect a neighbor across the street to be involved in something like that,” said Jerry Vining, Aldosary’s neighbor.

“I’ll be the most stunned person if it turns out he did something like that,” said Welsh.

Aldosary has served time for aggravated harassment after he threatened an employer who wasn’t giving him enough hours.

FOX 10 spoke with that employer Saturday and they say Aldosary made threatening calls and sent letters, but none mentioned explosives.

Aldosary is expected in federal court Monday.
