( CNN ) An Iraqi man watching his first snowfall in his new American hometown was shot and killed by an unknown assailant , according to Dallas police . Authorities have stepped up patrols in the neighborhood where Ahmed Al-Jumaili lived -- and died -- in their effort to find out who killed the 36-year-old early Thursday , as he and his brother stood in the parking lot of his apartment complex watching the snow . Al-Jumaili 's wife was with them taking photos . Dallas police spokesman Jeff Cotner said Al-Jumaili , who recently immigrated to the U.S. , had never seen snow and `` just like all of us , a pretty snowfall brings the child out in us . '' There is `` extreme heartache ... and no shortage of sadness for this beautiful young man who had just come to this country 20 days ago , '' said Alia Salem , executive director of the Council on American-Islamic Relations in the Dallas and Fort Worth area . CAIR became involved in the case immediately after the shooting , according to Salem , because of `` a heightened sense of awareness with regard to hate crimes against Muslims . '' Salem said the Muslim community wanted to know whether the shooting death was random or whether Al-Jumaili was targeted . Police say they have no indication so far that it was a hate crime . When shooting broke out , Al-Jumaili cried `` I 'm hit ! '' according to Cotner , basing that on statements from witnesses and the victim 's relatives . He ran to his apartment nearby and died a few hours later . Police did not say where Al-Jumaili was struck or how many times he was shot . Some residents reported seeing two to four men enter the apartment complex on foot through a vehicle gate before the shooting , according to Cotner . He said there was no interaction between the men and Al-Jumaili and his family . In black-and-white soundless surveillance video , one person who appears to be carrying a rifle is seen running just ahead of a second person , Dallas police Officer Monica Cordova said . The second person is shown walking at a slower pace , holding what appears to be a handgun in his right hand . Approximately 13 seconds later , another person comes into view and passes by the camera , followed by a fourth individual who is walking , she said . From the vantage point of the camera , it is difficult to make out any of the features of the suspects or even the gender , although police have said they are looking for four black males . Witnesses say multiple shots were fired from what is believed to be a rifle . Cotner said police are conducting tests to find out whether more than one rifle was used in the shooting , but he said he could not reveal the make or model of the weapon . Cotner said Friday that other than that , police have little to go on . `` We ca n't solve this crime alone , '' he said . Authorities are appealing to the public to contact them with any information that might help the investigation . North Texas Crime Stoppers is offering a $ 5,000 reward for information that leads to an arrest and an indictment , police said . Salem is encouraging anyone with information about the shooting to share it . She said there are online campaigns underway to help raise funds for the family 's expenses , as well as an effort to raise additional funds to contribute to the reward .
