ALBERTVILLE, Ala. -- A shocking crime in Marshall County led to the arrest of a teenager who is charged with raping his mother.

Albertville police say 19-year-old Gary Helms Junior is charged with first-degree rape. Police allege that he sought revenge against his brother after the two argued over a girlfriend and apparently targeted his 45-year-old mother.
