DENTON, Texas– Police say something posted on social media led them to the suspect in the murder of a Texas college student.

U.S. Marine Eric Jamal Johnson was arrested Tuesday at his base in an Arizona city near the Mexican border, some 1,100 miles from where he allegedly shot and killed 20-year-old Sara Mutschlechner, who had just rung in the new year at a party.

Mutschlechner was driving through the Dallas suburb with three passengers around 2 a.m. (3 a.m. ET) New Year’s Day. She was reportedly the designated driver and had not been drinking.  A gray Honda Pilot with five to six males inside pulled up next to them and the males started talking to them.

Police in Denton, Texas, say the conversation quickly went downhill and some “very derogatory” and “sexual” comments were made.  Then, shots were fired. Mutschlechner was hit and died at the hospital.

Witnesses from inside Mutschlechner’s car reportedly told police that two people who were in the Honda Pilot were at the party. One of them, they said, was a 16-year-old boy with braces.

According to CBS News, police used Twitter to find a boy who met that description. They said he posted that he was at that party. They then looked at other social media profiles and found one that showed a man with the teenager. Police say witnesses later identified him as the shooter. They also say the same man posted on Twitter a photo of a license plate of a BMW he owns. They discovered the car belongs to Johnson and found he also owns a gray Honda Pilot.
