Phoenix police have arrested the woman's brother-in-law, Bulmaro Tabera-Ramirez, 24, of Phoenix, who later allegedly admitted killing Corona and directed police to the location of the body.
According to the police report, Tabera-Ramirez was married to Corona's sister and the three lived together in Phoenix.
Phoenix Police Detective Tony Morales said that Tabera-Ramirez had driven Corona to a job interview, leaving their home on Dec. 12.
When Corona failed to return home that night, her family called police.
According to the police report, Tabera-Ramirez arrived home on Dec. 13 and claimed that Corona had been abducted by three men and was being held against her will somewhere in Camp Verde.
According to police, Corona's family said that the victim did not like the suspect, alleging he had previously made unwanted sexual advances toward her. After finding Corona's ATM card in the suspect's possession, they again called police.
According to the police report, Phoenix police interviewed Tabera-Ramirez on Dec. 14, obtained a warrant to search his vehicle and discovered evidence that led detectives to believe the victim may have been harmed.
According to Morales, Tabera-Ramirez had scratches to his face and blood on his shirt.
The police report states that Tabera-Ramirez changed his story and said that he was scratched when kidnappers forced him to put Corona in the trunk of his vehicle. Then he agreed to lead detectives to the home in Camp Verde where he said Corona was being held.
The report states that Tabera-Ramirez eventually admitted to detectives that he had sexually assaulted Corona in his car in Camp Verde then killed her at Oak Creek Canyon and dumped her body in the area.
On Dec. 15, Phoenix Police detectives, with assistance from the Coconino County Sheriff’s Office and U.S. Forest Service, located the victim’s body at the bottom of a canyon near the top of Arizona 89A. The exact cause of death is pending a medical examiner's autopsy in Prescott.
Tabera-Ramirez was booked into Madison Jail in Phoenix and faces charges of kidnapping, sexual assault and first-degree murder.
