Salt Lake police were looking Wednesday, Nov. 15, 2017, for Dyann Mariel Hernandez, 23, who is accused of stabbing her neighbor in the neck.

SALT LAKE CITY — Salt Lake police are looking for a woman with a history of violence who allegedly stabbed her neighbor in the neck.

The incident comes one day after Dyann Mariel Hernandez, 23, of Salt Lake City, was charged in a separate case with aggravated assault, a third-degree felony, and child abuse, a class B misdemeanor.

About 12:20 a.m. Wednesday, Salt Lake police say Hernandez came out of her house at 800 W. Arapahoe Ave. and stabbed her neighbor — who was also outside — multiple times in the neck.

Police say Hernandez and the man had been involved in an "ongoing dispute" and there was already "bad blood" between them. Investigators did not say Wednesday what kind of dispute the two were having or what may have sparked the latest incident.

The man was taken to a local hospital in critical condition.

On Tuesday, Hernandez was charged in an Oct. 24 incident in which she slapped a 12-year-old girl for allegedly "talking about her son," according to charging documents. When the girl's mother intervened, Hernandez choked the woman with both hands, the charges state. A $5,000 warrant has been issued for Hernandez's arrest in that case.

In December, Hernandez was charged with aggravated robbery after allegedly threatening her mother and another man with a knife, according to court documents. The case was later dismissed.

Anyone with information about the case are asked to call police at 801-799-3000.
