The mother of the boy now sits in a Denver jail, arrested on a charge of murder, police said Tuesday.
But the effort to name the boy — now known to be 7-year-old Liam Husted — took a police sketch, DNA testing and a concerned father to make it happen.
Husted had been with his mother, Samantha Moreno Rodriguez, according to his father.
He contacted the police in San Jose, California, about the missing pair on June 1, the Las Vegas police said during a press conference Tuesday.
The father told investigators that he had not seen or heard from his son or Rodriguez since he arrived May 24 at the home they shared in San Jose to find all of their belongings missing.
Rodriguez had reportedly left a message saying she and the boy were leaving him and she would find a new house for the two, Las Vegas Police Lt. Ray Spencer said at the press conference.
“There was nothing suspicious in that message that would lead the father to believe that Liam or Samantha were involved in any kind of foul play or that there was any harm, potentially to come over the next week,” Spencer said.
Not wanting to get Rodriguez in trouble, and having no reason to think Liam was in any danger, Husted’s father chose not to file a report of parental abduction, according to Spencer.
The boy was found dead by hikers on May 28 near the Mountain Springs Trailhead by State Route 160, according to the Las Vegas police.
Law enforcement immediately released sketches in an attempt to identify him. The National Center for Missing and Exploited Children also helped in the search.
The FBI offered a reward of $10,000.
Investigators then put out an enhanced image in hopes of getting information on the boy.
Crack in the case
On June 4, a friend of Rodriguez saw a sketch police had released to the media and contacted the San Jose Police Department, Spencer said.
Spencer explained that the friend told police that Husted could possibly be the child in the sketch.
Police in San Jose contacted LVMPD and investigators collected a pillow from Husted’s bedroom, said Spencer.
That pillow provided the DNA that allowed the Las Vegas police forensics lab to positively identify the body found on the trail as the 7-year-old from San Jose, according to Spencer.
Spencer said investigators have learned Rodriguez was seen at a hotel in Las Vegas on May 27 and they believe that Husted was still alive at that time.
