A woman was found dead on Sunday morning in the Carson City jail after she had been arrested on Saturday night, Sheriff Ken Furlong said.
The 23-year-old woman was arrested on a warrant from Lyon County. Her name has not been released.
Authorities had made contact with the woman and a man she was with during a domestic dispute that happened while driving, Furlong said.
Paramedics were summoned to the scene and she declined treatment. During booking she informed staff of minor medical issues, Furlong said.
The woman was checked throughout the night by jail staff and was awake and alert for breakfast, he said. A short time later, when food was brought to her, she was found unresponsive.
The cause of death is under investigation, Furlong said.
