HOUSTON (AP) — The first wife and a daughter of a Jordanian immigrant convicted of two slayings described by prosecutors as "honor killings" tell jurors he sexually assaulted them and subjected them to years of abuse.

The Houston Chronicle reports the women testified during the punishment phase of Ali Mahwood-Awad Irsan's trial.

A jury convicted Irsan last month of capital murder in the deaths of his son-in-law and his daughter's friend who had encouraged the marriage.

Irsan faces life in prison or the death penalty.

He has denied any involvement in the deaths.

On Friday, Robin Dahl, Irsan's first wife, told jurors he tried to poison her with cyanide tablets and used stun guns on their children. His daughter Nesemah testified Irsan tried to drown her.

The trial's punishment phase resumes on Monday.
