Jury in Kingman, Ariz., to decide on sentence for man convicted in slaying

KINGMAN, Ariz. — A jury in Kingman, Ariz., deliberated 45 minutes Thursday before convicting a Kingman man of the attempted murder of his estranged girlfriend and the murder of her teenage daughter.

The jury will return Monday to decide whether Darrell Ketchner, 55, will be sentenced to death or spend life in prison.

There was no dispute at trial that Darrell Ketchner stabbed to death 18-year-old Ariel Allison and stabbed and shot her mother Jennifer Allison, 38, on July 4, 2009. Jennifer survived the attack but the daughter who came to her aid died of her wounds.

Prosecutor Megan McCoy argued the attack was premeditated and defense attorney John Napper failed to convince the jury that the violence came in the heat of passion

Attorneys agreed they had a volatile and dysfunctional relationship.

Ketchner served two previous prison terms for drug case convictions.
