TOLLESON, AZ – An Arizona community is reeling after the brutal killing of an 18-year-old woman who vanished after meeting a man she connected with on a dating app, authorities said.
The victim, identified as Yessenia Norman, reportedly left her residence in a transitional program for young adults under state care on January 15, telling friends she was going to meet someone new. Days passed with no sign of her, prompting a friend to file a missing persons report on January 19. Police began searching for Norman, but it would be nearly two weeks before her disappearance would come to a devastating end.
On January 28, officers conducting a welfare check at an apartment in Tolleson, a suburb west of Phoenix, walked into a grisly scene. There, beneath a pile of towels and blankets, lay Norman’s body, showing evidence of a vicious attack. Medical examiners determined she suffered nearly 30 stab wounds.
Investigators quickly linked the apartment where Norman was found to 27-year-old Randal Basilio Santillan. Detectives secured a warrant for his arrest after evidence tied him to the crime scene, but Santillan had already fled Arizona, setting off a sprawling, multi-state manhunt.
Tracking his movements through a patchwork of traffic cameras, authorities followed Santillan’s vehicle as it crossed into New Mexico, then through Illinois and Missouri. The search ended more than 1,600 miles away, in Biloxi, Mississippi, where law enforcement located and apprehended the suspect without resistance on Friday.
Santillan was booked into the Harrison County Adult Detention Center as he awaits extradition to Arizona. He is facing charges of first-degree murder and kidnapping; authorities declined to provide a possible motive for the attack.
Family and friends are left struggling to comprehend the horror of Norman’s final moments. Loved ones described her as a compassionate and determined young woman, aspiring to build a better future for herself. She had recently enrolled in community college, eager to forge ahead into adulthood and explore her talents.
Norman, also known as Sisi, was remembered online as someone who deeply cared for her friends and their children, cherishing their bonds like family. Those close to her expressed disbelief that such violence could touch her life.
As the investigation continues, Norman’s death has sparked renewed concerns about online dating safety and the vulnerability of young adults navigating new relationships. The Arizona Department of Child Safety confirmed that Norman was enrolled in one of its transitional living programs at the time of her disappearance.
A fundraising campaign has been launched to support Norman’s mother and help with funeral expenses, with organizers sharing heartfelt tributes to the young woman’s caring nature and ambitions. Authorities urge anyone with additional information about the case to contact Tolleson police.
Santillan remains in custody out of state, expected to be transported back to Arizona to face prosecution in the coming days.
