Every firearm should always be treated as if it were loaded, even if you’re certain it’s not. One young Wichita Falls woman learned that lesson the hard way in May of 2014.

Britton Campbell, who was 19 at the time, had returned to the apartment of 26-year-old Justin Quintana, a former MSU student, after a night out. Quintana was showing off his gun collection to Campbell. According to KFDX TV reports, Campbell claimed that Quintana wanted her to point what both apparently thought was an unloaded weapon at him so he could post a video to Snapchat. She pulled the trigger and the gun fired. The round struck Quintana in the heart, killing him instantly.

KAUZ News Channel 6 reports that Campbell entered into a plea agreement in December. The now 21-year-old plead guilty to criminally negligent homicide and was sentenced to five years deferred adjudication and fined $1,000. She will not serve any jail time under the agreement. If Campbell successfully completes her sentence, the charge will be removed from her record. She is also prohibited from possessing any type of firearm for five years.

Several months after the May 2014 shooting, Campbell was indicted for manslaughter by a Wichita County grand jury. In December, she agreed to waive her right to trial by jury and agreed to the guilty plea on the single charge of criminally negligent homicide. Wichita County prosecutors were reportedly able to recover the Snapchat video that confirmed Campbell’s version of what happened on the night Quintana was shot.
