Herndon Police: Suspect in Elden Street stabbing identified, arrest made in 2019 rape case

A 41-year-old Herndon resident is facing an assault charge for a fight that ended in him reportedly stabbing another man.

According to a weekly crime report released yesterday (Wednesday), the Herndon Police Department has taken out a warrant for aggravated assault against Dennis Cruz Antunez for the stabbing, which occurred on Aug. 26 in the 1000 block of Elden Street.

Police say the incident started as a “verbal altercation” between the suspect and the male victim, who was transported to Reston Hospital with non-life-threatening injuries.

Herndon police also recently arrested a 21-year-old man for a 2019 rape.

“Oscar Martinez Alarcon, 21, of Herndon, was arrested for the forcible rape of a juvenile victim whom he met via social media,” the police report says. “He was transported to the Fairfax County Adult Detention Center where he was held without bond.”

According to police, the incident occurred on Feb. 12, 2019 in the 1200 block of Elden Street. Martinez Alarcon was arrested on Aug. 23.

The HPD did not return a request for comment from Reston Now on what led to the arrest and whether there might be any additional victims by publication time.

Other major incidents in the weekly crime report include three cases from Aug. 24: another verbal argument that escalated into a stabbing on Elden Street and two robberies in the 1200 block of Springtide Place.

Labeled as an aggravated assault, the stabbing occurred in the 1100 block of Elden Street. The victim was reportedly punched and stabbed. Police say they have identified the suspect, but the case remains under investigation.

In one of the robberies, the victim reported that he was assaulted and had his wallet stolen “by a subject that is known to him.” In the other, the victim was assaulted and had his wallet and “other personal property” stolen by two men.

According to the report, police have identified the subjects in both cases, which are still under investigation.

The Town of Herndon also saw 11 reportable traffic crashes during the week of Aug. 23-29, which are defined by Virginia State Police as incidents that result in injury or at least $1,500 in property damages.
