Ahmed Al-Jumaili, 36, was taking pictures in the snow in an apartment parking lot in the 9900 block of Walnut Street late Wednesday night when he was hit by random gunfire.
Police said Friday that multiple shots were fired from what they believe was a rifle.
Al-Jumaili was rushed to the hospital early Thursday morning but did not survive.
The suspects are believed to be a group of four black teenage males, who took off running from the scene after the shooting.
Witnesses told police there was a group of young men nearby, and one of them started firing shots without warning. There was no altercation at the scene between the victim and suspects.
Al-Jumaili had recently moved to North Texas from Iraq, where he grew up.
He married his wife, Zahara, 16 months ago. She came to the U.S. to join her family while he stayed in Baghdad, where he worked until he could join her. That reunion occurred just three weeks ago.
A representative of the Dallas-Fort Worth Council on American-Islamic Relations said at a Friday's press conference they have little reason to believe the shooting was a hate crime, but that members of their community are concerned.
Al-Jumaili was buried Saturday in Denton.
