Crystal Boyett, accused of causing a February accident that killed two Lumberton sisters and an unborn baby whose bond was increased to $2.4 million last week, posted bond Monday night and was released from the Hardin County jail. Boyett was out on a $2 million bond, $1.5 million for three manslaughter charges and an additional $500,000 for an aggravated assault with a deadly weapon added in an august grand jury and went back to jail after the judge ordered the bond increase Thursday.
