The victim was identified as 38-year-old Tiyanie Ly, a mother of three. Anaheim police said Ly and Alhasan were in a dating relationship.
Ly's body was found in a duffel bag early Tuesday morning behind an apartment complex on the 2100 block of S. Euclid Street. A person rummaging through a dumpster looking for recyclables discovered the body and called police shortly after 2 a.m.
After appealing for the public's help in finding Ly's missing vehicle, Anaheim police on Friday announced the minivan had been located.
It is still not confirmed where the crime occurred, and details surrounding the nature of the murder have not yet been released.
If convicted, Alhasan faces 25 years to life in state prison. He is expected to be arraigned on Nov. 15, according to the Orange County District Attorney's Office.
Ly's family said she cared about everyone.
"I miss her a lot, and I love her a lot," Vei Ly, the victim's father said.
Her father said he just wants his daughter back.
He knew something was wrong when she didn't show up to take her kids to school. Her children are ages four, eight and 10.
They couldn't get a hold of her and then started to see reports of a body found in a duffel bag in a dumpster.
"Your mind starts racing into like - 'Is it possible?' -- but the rational side of me says this is impossible," Adam Margaros, Ly's brother-in-law said.
Family said Ly kept her relationship with Alhasan fairly private.
"How could somebody put my sister in a bag and throw her in a trash can?" Margaros said.
The youngest child was said to be glued to his mother.
"The hardest part for me is, almost like, he knew that he didn't have enough time with her because he never wanted to leave her," Margaros said.
Anyone who may have dated Alhasan or was aware of his relationship with Ly is urged to contact police.
A GoFundMe account has been set up to support Ly's family. If you would like to donate, visit www.gofundme.com/in-memory-of-tiyanie-sopheap-ly.
