Forty-five year-old Efrain Muniz of Wichita Falls is on trial in the 89th District Court.
A doctor who examined the victim following the alleged assault testified during today's proceedings.
She says she found DNA from Muniz on the victim.
She also says she found DNA from another person on the victim but it was such a small amount that it couldn't be traced.
Police say the assault took place in Feb. 2011 in a home in the 21-hundred block of Ave. E.
