DESOTO, Texas — Update 4:24 Tuesday with additional information from an arrest warrant affidavit. 

A 21-year-old woman was stabbed to death in her front yard Monday night in DeSoto, police said. 

Officers responded around 8 p.m. in the 1200 block of Greenbrook Drive near and found the woman with multiple stab wounds. She has not been publicly identified.

Police say when they arrived at the house they found the woman lying in front of the front door in a large pool of blood.

Officials say the woman was unconscious and had lacerations to her face. 

The woman was transported to the hospital where she was pronounced dead, police said.

The victim’s parents told police the woman’s last words were, “It was Matthew, It was Matthew," according to an arrest warrant affidavit.  

Matthew Gonzalez, 20, is the victim's ex-boyfriend and is accused of threatening her in the past, the affidavit states. 

Gonzalez had allegedly threatened the victim with a knife in July after they broke up, according to the affidavit. 

The victim’s stepfather told police he saw a man who looked like Gonzalez running away from the house after finding his daughter on the front porch, the affidavit states. 

Gonzalez was arrested early Tuesday by Irving police on a murder charge, officials said.
