Omaha police arrested a man Monday on suspicion of homicide in the October shooting death of 16-year-old Eriana Carr.
Tracy Parnell, 21, had been charged with other offenses possibly related to the Oct. 30 shooting, and police said for months that they considered him a person of interest in Eriana's death.
Eriana suffered multiple gunshot wounds and died shortly after being taken to the Nebraska Medical Center. Her cousin, Nakia Johnson, who was 20 at the time, was shot 11 times but survived.
Parnell had been in the Douglas County jail since March when he was arrested on the homicide charges Monday.
Some of his earlier charges resulted from an incident that occurred days before the shooting, when, police said, he threatened Johnson at gunpoint. At the time, Johnson was a roommate of Parnell's girlfriend. Parnell, a Crips gang member, was angry at Johnson for inviting her boyfriend, a Bloods gang member, to the women's apartment, police said.
Parnell was charged with making terroristic threats, use of weapon to commit a felony and possession of a firearm.
In March, while out on bail after the terroristic threats arrest, Parnell hit an ex-girlfriend's car with a hammer, police said. He was charged with felony criminal mischief.
Monday's arrest brought new charges: first-degree murder, felony assault, two counts of use of a weapon to commit a felony and possession of a firearm by a felon.
An earlier version of this story said Tracy Parnell had been convicted of the felony criminal mischief charge.
