Still, Teare said investigators were able to piece together the case through cellphone data, surveillance video and other evidence collected during the investigation.

Family still searching for closure

While Thursday's verdict brought a measure of justice, it did not bring complete closure for Rodriguez's family.

Prosecutors alleged Arceneaux dismembered Rodriguez with a chainsaw and disposed of her body. Her remains have never been found.

 It's been hard for the family,  Jimenez said.  Destiny has grown up eight years of her life without her mother. It's hard. 

Arceneaux is expected to return to court Monday for the punishment phase of the trial, when the same jury will determine his sentence. The worst possible punishment is life in prison without the possibility of parole.
