Altaf Hussain Malik, 43, disappeared last Tuesday after he went to meet someone who was interested in buying his car.
Two days later, Malik's body was found stabbed near a dumpster in the Third Ward.
His wife Quratulain Malik tells Eyewitness News her three younger kids still don't really know what happened, but her oldest is struggling with her sadness.
"When you see her, you can see the grief on her face. She started crying. Right now, she's confused about going back to school because she says, 'I don't want to face people asking me questions about what happened,'" Malik's wife said.
Malik also says she's thankful for all of the support, but she wants justice.
