A Louisiana sheriff says the wife of a man accused of killing a pastor filed a rape complaint against the preacher two days before he was killed.

However, Calcasieu Parish Sheriff Tony Mancuso said Monday that investigators are trying to determine whether the woman's relationship with the pastor was consensual.

Mancuso says the woman and preacher had exchanged text messages, and it's not yet clear whether a sexual assault took place.

Woodrow Karey is charged with fatally shooting Ronald Harris Sr. during a service Friday at the Tabernacle of Praise Worship Center in Lake Charles. The rape complaint was filed Wednesday.

Authorities say Karey called to surrender minutes later and directed deputies to a shotgun and a .22-caliber pistol he had left in nearby woods.
