On May 8, 2018, 21-year-old Joshua Hilaire walked into the Tucson Police main station downtown and turned himself in to detectives in connection with the murder of 18-year-old Rosaura Hernandez.
Homicide detectives interviewed Hilaire and then booked him into the Pima County Jail on his arrest warrant for First Degree Murder.
On May 6, 2018, just after 7:00 p.m., Tucson Police officers responded to 1254 S. Craycroft Road for a check welfare call. Family members were concerned about Rosaura, who called to tell them she was fighting with her live-in boyfriend and needed a ride. Family went to the apartment, but there was no answer at the door. When officers arrived, there was still no answer at the door and they were unable to reach her by phone. At that point, police did not know if Rosaura and her boyfriend had left the apartment or if she had possibly received a ride from someone else.
Approximately two hours later, officers responded back to the apartment after learning that family members had forced entry into the home and found Rosaura injured and unresponsive. When officers entered, they found Rosaura with obvious signs of blunt force trauma and pronounced her deceased on scene. Hilaire was not at the home.
