A 19-year-old man shot and killed his girlfriend “without any intention to do so” at a Lawrenceville home early Thursday, according to police and an arrest warrant.

Lawrenceville police responded to a home in the 900 block of Lauren Kay Court around 1:20 a.m. and found the woman in an upstairs bedroom with a gunshot wound to the head. She was pronounced dead at the scene and later identified by officials as 19-year-old Nina Ramirez.

Her boyfriend, Sebastian Prestridge, shot her in the face, according to the arrest warrant obtained by The Atlanta Journal-Constitution.

In a GoFundMe created to amass money for Ramirez’s funeral, she was described as passionate and fearless.

“Though Nina’s time with us was heartbreakingly short, her impact will last forever. She will be remembered for her courage, her humor, her loyalty and the love she gave so freely to everyone around her,” Logan Ramirez wrote on the GoFundMe campaign.

Prestridge was charged with felony involuntary manslaughter and was in the Gwinnett County jail as of Saturday morning. Police said he remained at the scene and was detained without incident.

“This is an incredibly tragic situation, and our hearts go out to the victim’s family and loved ones,” Lawrenceville police spokesperson Capt. Dena Pauly said in a statement.

The investigation is ongoing, she added.
