An 18-year-old has been arrested in connection to a traffic crash that killed a woman and her grandson in Mississippi, police said Wednesday.

Izaun Cade Baxter faces two counts of manslaughter and other charges, WDAM-TV reported. The charges follow the deaths of 59-year-old Ollie Armstrong and 7-year-old Kevin North Jr. on Oct. 10.

The rollover crash happened on U.S. Highway 90 in Biloxi. Police said an investigation determined that Baxter was driving recklessly when his car hit the one driven by Armstrong.

Baxter was arrested Monday and was jailed with bond set at $300,000. It’s unclear whether Baxter had an attorney who could comment on his behalf.
