Erskine grew up in southern California. When he was five years old, Erskine darted into traffic on the Pacific Coast Highway in Long Beach and was hit by a station wagon. He remained in a coma for 60 hours. Although physically he appeared recovered, he frequently complained to his mother about headaches, and he experienced "black-out" moments where he could not remember what he was last doing. At the age of 10, he started molesting his 6-year-old sister, forcing her to perform oral sex upon him. He soon began abusing her friends, threatening to kill them if they told anybody. Erskine attended Southwest Junior High School in San Diego, California and was placed in "special classes" for the emotionally disturbed. At 15, Erskine escaped from a juvenile detention facility, pulled a knife on a 13-year-old girl and raped her. The next morning, he assaulted a 27-year-old female jogger with a knife. In 1980, while on his way to interview for a camp counselor's position, Erskine beat a 14-year-old boy unconscious during an attempted rape. He also raped another inmate while imprisoned. Erskine begged the San Diego judge at the time to spare him from adult prison. Despite his mother's pleas to send her son to a mental institution, Erskine was sentenced to four years in prison; he was paroled in 1984. In 1993, Erskine invited a woman, who was waiting for the bus, into his home and held her hostage for several days, repeatedly raping and sodomizing her before letting her go. He was quickly arrested. He was convicted of rape and kidnapping, required to register as a sex offender, and sentenced to 70 years in prison. As a convicted sex offender, Erskine had to submit his DNA to a database. In March 2001, the San Diego Cold Case squad reopened the investigation of the unsolved 1993 murders of nine-year-old Jonathan Sellers and 13-year-old Charlie Keever. The police tested cotton swabs taken from Keever's mouth at the time of death, that contained semen. The DNA sample was entered into CODIS, and was matched to Erskine.
The trial
In September 2003, Erskine went on trial for the two murders. The jurors were shown photos of the crime scene: Sellers was at the entrance of the makeshift fort hanging from a castor bean tree branch. He was naked from the waist down, his legs and arms bound with rope, and his mouth gagged. His genitals showed obvious signs of sexual assault, and a noose was tied around his neck. On the ground lay Keever, his head resting on a pile of his and Sellers' clothes. He was also naked from the waist down, legs and arms bound, his mouth gagged, and his genitals were bleeding from extensive bite marks. He, too, had a rope around his neck. The pathologist determined Charlie Keever was alive when the bite marks were inflicted. Erskine's DNA was also found on two cigarette butts found near the bodies. Erskine's public defender never denied Erskine killed the boys, but instead focused on Erskine's car accident when he was 5 years old. The public defender stated that Erskine received serious brain injuries that diminished his capacity for right and wrong. They argued that life without the possibility of parole was a more appropriate punishment. On October 1, 2003, the jury found Erskine guilty of murder; however, they could not agree on the sentence. Eleven jurors voted for the death penalty, while one juror voted for life without parole. The judge declared a mistrial on the penalty phase. In April 2004 Erskine went before a second jury to decide his punishment for the murder. This jury returned a verdict of death. On September 1, 2004, a California judge affirmed the jury's verdict and gave Erskine the death penalty. He was transported to San Quentin six days later.
Florida murder
While awaiting the start of his trial, Florida investigators matched Erskine's DNA in the unsolved case of 26-year-old Renee Baker, who was murdered on June 23, 1989. He was formally charged in 2003, and was sentenced in August 2004. Erskine, who lived in Palm Beach County, Florida, at the time, admitted to raping and killing Baker, and was sentenced to life without parole. Baker drowned when Erskine broke her neck and left her near the bank of the Intracoastal Waterway in Palm Beach. Florida authorities suspect Erskine may be linked to other unsolved homicides.
Death
Erskine died on July 3, 2020 after contracting COVID-19. He was 57.
