North Charleston police: Boy, 9, shot sister, 7, with mother's gun while home alone

A 9-year-old boy accidentally shot his 7-year-old sister Friday evening while the two were alone at their North Charleston home.

Police say the gun belonged to their mother, who had left the firearm in the couch. After the shooting, officers say the two children ran down the street to a neighbor's house for help.

The mother, Shaneice Dent of Clifton Street, was charged with unlawful conduct toward a child. She also faces drug charges. Saturday morning a judge set bond amounts for Dent's charges - $75,000 for unlawful conduct towards a child $25,000 for manufacturing cocaine base $5,000 for cocaine possession and $5,000 for possession of heroin.

Dent's boyfriend, Anthony Samuel, is charged with misprision of a felon. His bond amount for the charge is $75,000.

The wounded girl was taken to MUSC for treatment. Police did not have an update on the girl' condition late Friday night.

The shooting happened two blocks away from another accidental shooting that happened about an hour earlier.

Police say the first shooting, which left a 15-year-old with a gunshot wound to the groin, was self-inflicted.

Investigators say the teen confessed that he and several other kids were playing with firearms in the area of Bolton Street and Piedmont Avenue. The injured teen ran from the area, tripped on railroad tracks, and shot himself, police said.

The shootings are not related, police said.

Police are still investigating both shootings.
