‘I told her all the time.



‘You’re just barely about to graduate high school. You don’t need to be worried about this. You can always find someone else.’

Another friend told the website the young couple’s relationship was ‘toxic.’

Riojas, who was due to graduate this summer, ditched Nickerson last week after suffering physical and violence abuse from him.

He slashed the tyres on her car, with talented dancer Riojas confiding in Coy that she was planning on blocking him on social media in a bid to remove him from her life.

After the killing Riojas’ younger sister who also lived in the apartment dialed 911.

That sparked a huge manhunt, with cops later discovering Nickerson’s lifeless body with the gun he had used to kill his ex and himself still in his hand.

After the tragedy Highlands High School Facebook page wrote: ‘It is with deep sadness that I inform you of the deaths of seniors Clarissa Riojas and Louis Nickerson which occurred this morning off campus.

Their deaths have shocked and saddened the Highlands community.’

San Antonio Police Chief William McManus added: ‘We have a very, very, seriously tragic incident that happened here this morning.

‘I’m the father of an 18-year-old myself, and I know the whole dating routine.

‘I guess the lesson learned the hard way is if you’re a parent with a daughter who’s dating, make sure you pay attention to the status of that relationship once it’s over.’
