Michigan synagogue attacker's ex-wife warned 911 operator he was 'not stable' as assault began

After he engaged in gunfire with security, Ghazali suffered a self-inflicted gunshot wound, according to the FBI.

At 12:21 p.m., Ghazali's ex-wife called 911 and told the operator that "His voice is not stable," referring to her ex-husband, adding that she had just spoken with him, according to records.

"I just want to make sure he's OK," she said.

Ghazali said that her ex-husband was "mentally unstable due to all his family dying overseas in the war." She said that Ghazali asked her to "send money overseas" before ending the call.

The suspect's ex-wife also said that Ghazali had been deeply distressed after two of his brothers along with their kids were killed in an Israeli airstrike.

On Sunday, the Israeli Defense Forces said that Ghazali's brother was a member of Hezbollah.

"His brother, Ayman Muhammad Ghazali, carried out the terror attack in Michigan this past Thursday. Ibrahim was eliminated in an IAF strike on a Hezbollah military structure last week," the post said.

One of the purchases came at 2 p.m. for $1,369.02 and the other was for $881.94 at 2:17 p.m. The items he purchased included inclined aerial repeaters, firecrackers and a fountain product.

Alan Zoldan, executive vice president of Phantom Fireworks, previously told Fox News there "was nothing really too suspicious" about the purchases Ghazali made and said that it seemed like he was "in a good mood."
