HILLSBOROUGH COUNTY, Fla (WFLA) – A 21-year-old woman accused of murdering her mother and stepfather heard “screaming voices in her head” then began thinking about killing her mother, according to documents released Monday afternoon by the Hillsborough County Sheriff’s Office.
Detectives say Nicole Gene Nachtman, 21, shot and killed her mother Myriam Carey Dienes, 56, and her stepfather Robert Dienes, 67, who lived in Carrollwood Village.
Their bodies were discovered at 9:26 p.m. on Aug. 20 when deputies responded to a 911 call about multiple shots fired at 14108 Fennsbury Dr. Deputies found the body of Myriam Dienes in the driveway of 14108 Fennbury Dr. and then found the body of Robert Dienes inside a nearby home at 14110 Fennsbury Dr.
Detectives identified Nachtman as the suspect in the shooting and obtained an arrest warrant for her. Nachtman was arrested in Tallahassee and was held at the Leon County Jail until she was extradited to Hillsborough County on Monday.
Late Monday afternoon, the sheriff’s office released new details about the case. An arrest warrant said that the Dienes’ neighbors told detectives they saw Nachtman near an open window and by the side garage door at 14110 Fennsbury Dr. within two hours of when a 911 call was made about shots fired.
Homicide detectives responded to Florida State University where Nachtman is a student. They spoke to a witness who said that Nachtman told the witness that she drove to Florida State University campus to pay for her dorm room. While she was at the campus, she continuously heard screaming voices in her head and began thinking about killing her mother.
Nachtman allegedly told the witness she began seeing signs on campus inferring that her dreams were about to come true and traveled back to her parents’ home. Nachtman allegedly told the witness that she shot her stepfather, killing him and said that when she shot him the screaming voices in her head began to fade and she thought to herself that “she could do this.”
Nachtman told the witness that she waited overnight for her mother to return home. When her mother returned home, Nachtman began having second thoughts about killing her and tried to leave through her bedroom window. Nachtman’s mother saw her and confronted her, asking why she was not at FSU. Nachtman then allegedly shot and killed her mother outside the residence. Nachtman told the witness she blacked out,then left the home after she came to.
Autopsies found that Myriam Carey Dienes was shot once in the neck and twice in the torso. Robert Dienes was shot once in the neck, according to the arrest warrant.
Myriam Dienes, was a reserve Navy captain who had just returned from reserve duty prior to her death.
Nachtman was booked into the Orient Road Jail on Monday and was charged with two counts of first degree murder with a firearm.
