Police showed up at an apartment off 91st Avenue near I-10 on January 28, 2026, just doing a standard welfare check. But what they walked into flipped this quiet spot west of Phoenix into a nightmare crime scene. There, under a pile of blankets and towels, was the body of 18-year-old Yessenia Gabriella Norman, stabbed 27 times. The Maricopa County Medical Examiner’s office didn’t hesitate they called it homicide right away.
Yessenia was trying to get her life together in a transitional housing spot run through Arizona’s Department of Child Safety. Her mom, Jessica Calderon, opened up in some local chats, her words heavy with grief.
“Who could do something like that to her?”
She asked, and you could hear the heartbreak. Friends talked about her as a girl with so much ahead, but she was dealing with the tough side of growing up independent, even with state help after some rough patches.
A tweet from X.
It all started with an online connection. She linked up with 27-year-old Randal Basilio Santillan on a dating app, chatting for a few days before meeting in person. Ring footage from January 15 shows her slipping out of her Phoenix place around 2 a.m. to see him. Phone records put both their devices in the same area that night, per the court docs. It was meant to be a casual hangout, but cops say it went horribly wrong at Santillan’s apartment the one he rented after his ex-wife left back in December 2025.
Investigators think he drew her there, and between 2 and 4 a.m. on the 16th, she was attacked with multiple stabs. Her roommate flagged her missing to Phoenix PD on the 19th, but it was over a week before that check revealed the horror. The lease in his name pretty much nailed him as the main suspect. Tolleson police described the scene as brutal, though they’re keeping any motive under wraps for now.
Santillan didn’t hang around long. He took off from Arizona soon after, cruising through New Mexico, Texas, Missouri, and Illinois, all the way to Mississippi. Cameras and plate readers followed his 1,600-mile drive, and on February 6 around 7 a.m., Biloxi cops with FBI backup nabbed him at a trailer park in 200 block of Baker Street. No fight; he’s locked up in Harrison County jail.
He’s staring down first-degree murder and kidnapping charges back in Arizona, with extradition coming. Prosecutors laid out the case in a complaint, from digital footprints to the bloody details at the scene. As of February 9, 2026, no plea or court date yet.
This whole thing shines a light on the dangers of online dating. Back in 2020, Pew Research said 35% of folks using apps get unwanted explicit stuff, and 9% deal with actual threats of harm. And from 2017-2020, about 14% of assaults involving people who met online came from apps, according to a Just Science Podcast breakdown. It’s a reminder to stay sharp out there.
But let’s not lose sight of Yessenia her story matters more than the mess. People are wondering about the why and if the housing setup could’ve done more, but we gotta stick to what’s known, not guesswork. While Calderon mourns, the fight for answers keeps going.
