In a significant development, law enforcement officials arrested a 17-year-old male on May 5, suspecting him of being involved in the murder of a 61-year-old woman, whose lifeless body was discovered on April 21.
The local media outlet, Las Vegas Review-Journal, has identified the suspect as Dennis Geiggar. Geiggar is a high school student who reportedly has a history of behavioral difficulties and incidents related to anger management.
Geiggar is accused of taking the life of Marceline Biasini, a 61-year-old woman who, according to reports from the Review-Journal, frequently spent her nights sleeping in the vicinity where she was found dead.
The tragic discovery was made just after 8 a.m. on April 21. The Las Vegas Metropolitan Police Department informed Fox News Digital that Biasini was discovered lying on a sidewalk outside a business establishment, suffering from evident injuries.
Surveillance footage from the area provided crucial insights into the case. The Review-Journal, referencing police records, reported that the video captured a brief and suspicious encounter during the early hours of the morning. It showed a suspect approaching the location where the victim was found and departing only a minute later.
Though the video did not directly capture the act of murder, it allegedly recorded the sound of a loud scream followed by approximately 61 loud impact noises, raising suspicions about the nature of the encounter.
“The precise location of the crime scene was obstructed from surveillance cameras, but video surveillance with audio … captured the suspect approaching Marceline’s location and, seconds later, a scream is heard followed by approximately 61 loud thuds,” the Review-Journal report said.
Detectives determined the woman had been “battered at some point during the night,” according to a statement provided to Fox News Digital.
The Clark County coroner’s office ruled Biasini’s death a homicide, citing blunt head trauma, according to the Review-Journal.
Geiggar reportedly has a history of anger issues and troubled behavior.
He was expelled from Valley High School in January after allegedly attempting to start a fire on campus, the Review-Journal said, adding that he has since been attending school online.
Police also said Geiggar had “numerous incidents where his anger had resulted in his punching walls and trash cans” and had been participating in anger management classes, according to the outlet.
According to police reports, surveillance video from a nearby 7-Eleven showed a suspect wearing a red hooded sweatshirt and Vans shoes, clothing Geiggar was reportedly seen wearing while attending Valley High School.
In addition, detectives reportedly found bloody footwear impressions at the crime scene.
Tests on Geiggar’s Vans shoes came back presumptively positive for blood, though DNA comparison has not yet been completed, the outlet said.
Police added that Geiggar’s physical description matched that of the suspect.
Documents state Geiggar has denied the accusations, though he acknowledged visiting a 7-Eleven nearby around 1–2 a.m. with his older brother, the Review-Journal reported.
Video from that store reportedly did not show him inside at that time.
Geiggar has denied the accusations, according to documents cited by the Review-Journal. It was not immediately clear whether he had retained an attorney who could comment on his behalf. He has not been convicted in connection with Biasini’s death, and the case remains pending.
Geiggar has been taken into custody on one felony count of open murder, a charge alleging homicide without specifying the degree of the offense.
