RALEIGH — At the Amtrak station on West Cabarrus Street late Thursday, police charged a New Jersey woman with the state’s most serious heroin trafficking felony minutes after the Silver Star train from New York City’s Pennsylvania Station arrived.

Delia Maria Webber-King, 46, of Morristown, N.J., faces two counts of trafficking in heroin, one for possessing and the other for transporting what police said in an arrest warrant was more than 28 grams – about 1 ounce – of the drug.

State law lists three levels of felonies for heroin trafficking and rates any quantity over 28 ounces the same.

Police did not disclose how much heroin they found.

The Silver Star is scheduled to be in Raleigh at 9 p.m. Webber-King was arrested at 9:15 p.m., an arrest report said.

Webber-King was held Friday in lieu of $500,000 bail.
