Catina Salarno was shot to death by Burns on her first day at the University. The complete investigation behind Catina's murder is documented in the 48 Hours episode, The Boy Across the Street. The episode is set to make its release on May 3, 2025, at 10 pm EST.
What is the story of the 48 Hours subject, Catina Salarno?

As reported by CBS News, Steven Burns and his family first moved to San Francisco and started living across the street from Catina's family residence in 1977. Catina was a student at an all-girls high school. As per the Record Net, Steve was a promising football athlete from St. Ignatius High School, located in San Francisco.
Reportedly, the 48 Hours episode subject, Catina Salarno, started dating Steven Burns, which continued for three years. As reported by Record Net, it was during the summer of 1979 when Catina tried to break up with Steven, as she had plans to move to the University and pursue her career in dentistry.
However, she had no idea Steven had also enrolled in the University. Steven Burns had a troubled relationship with his father, and hence, Catina's father took him as his godchild. Nina Salarno, Catina's younger sister, revealed that Burns showed very aggressive traits while being in a relationship.

She revealed that there were some instances when Steven Burns threatened to kill Catina Salarno. But as per Nina, the 48 Hours subject never took the threats seriously. Catina's middle sister, Regina, said that none of them could believe his threats because the family had come to trust Burns over the years.
Nina Salarno herself went on to become a prosecutor specializing in domestic violence cases. She has served the position of Modoc County District Attorney since 2023, as reported by CBS News. Talking to 48 Hours, she revealed how most of the domestic crime victims miss the prior warnings from the killer.
"I think this is what's rerd for domestic violence victims — they really don't think the person's gonna kill them … in a lot of the situations they think … they know this person … And I think that's exactly what happened with Catina is she just figured his comment was just his comment. Even though he had made threats, she could handle it, 'he's never gonna cross that line' type thing," Attorney Nina Salarno said.
