Girlfriend, family testify in "American Sniper" case

STEPHENVILLE, Texas -- Eddie Ray Routh's girlfriend, sister and brother-in-law took the stand Wednesday as defense attorneys argued the defendant was in a psychotic state when he killed "American Sniper" Chris Kyle and his friend Chad Littlefield.

Routh and girlfriend Jennifer Weed had a troubled relationship, Weed said. She told the Erath County jurors she had agreed to marry him the night before the murders but that they nearly broke up after a big fight the next morning, reports CBS DFW.

"I asked him if he was seeing things, and he said yes, and then I asked him if he was hearing things, and he said yes," Weed said, describing a conversation they had the night before the killings.

"He definitely had paranoia, about the government out to get him," Weed said. She also told the court that Routh, 25, would go weeks without showering and described about an incident when Routh, armed with a sword and knife, would not let her or her roommate leave their apartment.

Earlier in the morning, Routh's brother- in-law Gaines Blevins testified that Routh came to Blevins' house on the evening of Feb 2, 2013 right after the murders. Gaines said his hair stood on the back of his neck when, "(Routh) said he had taken two souls before they could get me."

Routh's sister, Laura Blevins said at first she did not believe her brother when he confessed to killing Kyle and Littlefield. On the stand, she said he was "talking nonsense" and "in a daze" the night of the killings.

But then she saw Chris Kyle's truck in her driveway, the same truck he was driving when he was caught by police.

She told him, "I love you but I hate your demons."

The prosecution has argued that Routh was purposely putting on a facade and was a man in control of his actions - not someone, as his insanity defense claims, who did not know right from wrong. Prosecutors said earlier in the trial that he showed he knew right from wrong when he fled in Kyle's truck for Oklahoma.

The trial continues today.
