PAPILLION, Neb. (AP) _ A man repeatedly injected his teen-age daughter and two of her friends with methamphetamine, prosecutors said Thursday.

Dennis Avery, 50, is charged with child abuse, drug distribution and possession. The drug counts alone are punishable by up to 20 years in prison and a $25,000 fine.

Authorities say Avery injected methamphetamine into the arm of his daughter, now 16, and her two friends, now aged 16 and 17.

Prosecutor Tricia Freeman said Avery injected two of the girls 20 to 30 times, and one possibly 75 times with a substance he called ``crank,'' which is a slang term for methamphetamine.

In closing arguments of a four-day trial, defense attorney Gregory Pivovar said Avery was a methamphetamine addict, but prosecutors failed to prove he gave the drug to the children.

``Dennis Avery is a cool dad who tried to be a cool guy,'' Pivovar said. ``He tried to impress them with the fact that he did meth.''

Sarpy County District Judge William Zastera will announce a verdict in the bench trial Friday.

Two of the girls testified that Avery made sexual advances to them, paged them at school, and one said he wrote her love letters and made a collage of her photographs.
