Jesse Robert Pincince, 37, was in custody early Monday on $350,000 bail after his arrest on more than a half-dozen charges, including second-degree manslaughter, misconduct with a motor vehicle and negligent homicide with a motor vehicle, Lt. Matt Carl said.

Police didn’t release the girl’s name but said she was a student at Enfield High School. “She died March 6th,” Carl said.

According to police, 911 callers alerted state troopers to an erratic driver on I-91 about 3 p.m. Sunday. While he was not proven to be under the influence, he was texting a driving. The male driver got off the highway in East Windsor, and local police got a call from a woman who was driving behind the man. She said she was stopped at a red light at the intersection of routes 5 and 140, and that the erratic driver had gone through the light. The teenager had been walking on the side of the road with another girl, who was 12; there is no sidewalk there.

The teen was taken to Connecticut Children’s, here she died about 8 p.m., Carl said. Police have not release her name at the family’s request.

On Monday, Enfield Superintendent Christopher Drezek released a statement saying, “Yesterday, we tragically lost a 14-year-old Enfield High School student. Our crisis team was in place at Enfield High School before students arrived this morning, and we have grief counselors for students and staff at Enfield High School all day today and for the foreseeable future as needed. The entire Enfield Public Schools community is heartbroken by this news and is committed to helping this student’s family, and all of our students, deal with this unthinkable loss.”
