Murder investigation focused on four areas
(Rock Springs, Wyo. - August 31, 2012) Law enforcement officials in Rock Springs today (Friday, August 31) described the four areas of particular concentration in their investigation of the murder of 17-year-old Rigoberto Alvarado, whose body was found in a shallow grave outside Rock Springs on August 19 by a group exploring the long-abandoned remains of coal camps and coal mining operations.
The case’s timeline - tracking Alvarado’s movements from 8:30 PM on the night of July 29, when he left his family’s home at the Imperial Apartments in Rock Springs - continues to be of prime importance, Sheriff County Sheriff Rich Haskell and Chief Mike Lowell of the Rock Springs Police Department said on Friday. Alvarado’s father, Rigoberto Alvarado, Sr., reported his son missing to the Rock Springs Police Department the next morning, July 30, when he did not return home.
Investigators report that they have advanced the timeline considerably, and have identified several people who were in Alvarado’s company that night.
110-plus interviews have been conducted by city and county detectives since Alvarado’s disappearance. Polygraph examinations have come into play, and one individual who was scheduled for a polygraph failed to appear for an appointment.
Detectives and crime scene technicians have collected hundreds of items of evidence in the case thus far, including DNA evidence, all of which has been submitted to the Wyoming State Crime Laboratory in Cheyenne for forensic examination and analysis.
Cause of Death
According to detectives, Alvarado suffered several types of violent injury, any one of which could have been the cause of death. The nature of those injuries is being withheld for the time being while the forensic examinations are ongoing.
Alvarado, whose family moved to Rock Springs from the Pomona, California, area, attended the Rock Springs High School. He was known as "Rigo" or "Junior" to his friends. A $5,000 reward is being offered for information resulting in the arrest and conviction of persons involved in his death. Anyone who has such information is asked to contact either the Rock Springs Police Department at (307) 389-0264 or the Sweetwater County Sheriff’s Office at (307) 350-4010.
Calls will be handled with discretion.
