Teen 'senselessly and brutally murdered'; Sheriff

The man accused of murdering a 13-year-old girl on the Fourth of July did not know the girl, according to Orange County Sheriff John Mina.

The Orange County Sheriff's Office released new details on Friday in the case of a 13-year-old girl murdered last week. 

Sheriff John Mina said 28-year-old Jerry Dorisme, the man accused of killing Rose Thalie Dieujuste, was spotted on video purchasing the same kitchen knife that was found at the murder scene. Additional video showed Dorisme walking at a distance behind Dieujuste as she walked through the complex to her friend's house. 

Dorisme is facing one charge of first-degree felony murder after the teen was found unresponsive inside an apartment off South Rio Grande Ave. According to deputies, Dieujuste showed "obvious signs of trauma." She was rushed to the hospital, where she later died.

Man spotted buying murder weapon at store

A man accused of murdering a 13-year-old girl in Orange County was allegedly spotted on video purchasing the murder weapon at the store before the incident, Orange County Sheriff John Mina said.

Dorisme also has a criminal history and was recently baker-acted following an encounter with law enforcement just a few weeks ago. 

According to Sheriff Mina, deputies responded to reports of a man walking down the street with a knife. During the interaction with deputies, Dorisme punched three deputies. He was held for a mental health evaluation and later released. 

Previously, Dorisme was arrested for lewd and lascivious behavior towards a child, but the charges in that case were dropped. At this time, it is unclear as to why the charges were dropped.
