Delaware State Police Madison Sparrow

Authorities in Delaware have arrested the ex-boyfriend of a 17-year-old high school student whose beaten and battered body was found Saturday in a secluded, heavily wooded area of Newark.

Madison Sparrow was reported missing Friday night when she did not return home after a visit to the University of Delaware campus.

A junior at Newark Charter School, Sparrow was allegedly killed by her ex-boyfriend, 19-year-old Noah Sharp.

Local reports indicate Sharp is a graduate of the Newark Charter School.

A statement from Delaware State Police alleges "detectives obtained information through investigative interviews that Madison responded to an area in Newark where her ex-boyfriend, Noah, was located."

The statement continues: "The investigation revealed the homicide occurred in the Newark area due to blunt force trauma to her body. After the homicide occurred, she was transported to a secluded wooded location in Newark, where law enforcement officers discovered her body."

The Newark Post, citing court records, reports Sparrow was beaten to death with an aluminum baseball bat. Detectives recovered the blood-spattered bat from the same wooded area.

Sharp has been charged with first-degree murder, possession of a deadly weapon during the commission of a felony, and first-degree conspiracy. He's being held on $1 million cash bail.
