Police in Fairfax County said they are looking for a man who assaulted family members, carjacked a vehicle at knifepoint, kidnapped the driver and led officers in a chase throughout the D.C. area this weekend.
Herndon police said Cristian Alvarenga Aguilar, 25, remains at large and should be considered armed and dangerous. He is wanted in connection with an in-home attack around 9:30 p.m. Saturday in the 1000 block of Knight Lane.
Mr. Alvarenga showed up at a relative’s house that night and began wrecking the place, authorities said. He assaulted family members, brandished a knife to force one victim into the car, and stole the vehicle.
Police pursued the suspect from Virginia into the District and eventually into Prince George’s County. The suspect bailed out of the vehicle in Oxon Hill and left the victim unharmed, authorities said.
Mr. Alvarenga faces charges including robbery, assault, carjacking, abduction, reckless driving, driving without a license and preventing someone from calling 911.
“We’re very familiar with Cristian Alvarenga as it goes with Herndon Police Department, somebody that has a long history with us and charges,” Herndon police spokesman Ian Biggs told WTTG-TV.
Herndon police describe Mr. Alvarenga as an MS-13 associate with a lengthy rap sheet in the Virginia city.
Police documents shared with The Washington Times said officers have arrested him for carjacking, car theft, burglary, sex offenses, petty theft and assault since 2019.
But almost none of those major offenses are listed in Virginia’s judiciary records.
Court documents show Fairfax County prosecutors dropped assault and car theft charges against Mr. Alvarenga after he was arrested in September.
In 2022, Loudoun County prosecutors secured a misdemeanor theft conviction against Mr. Alvarenga. He was sentenced to 180 days in prison, but had 135 days of the sentence suspended.
The judiciary site said Mr. Alvarenga was arrested in December 2020 on car theft and extortion offenses. The case was sent to a grand jury and its outcome is not readily available to the public.
