A Serial Killer From the U.S. Preyed on Young Women in Canada · Murder Files Unsealed

  Speaker 1: Authorities suspect that the deceased individual, who passed away in
• 0:04
  an Idaho correctional facility may be connected to the unresolved
• 0:08
  homicides of several women in British Columbia, Alberta, and various
• 0:13
  locations across the United States. The serial offender exhibited minimal
• 0:18
  attempts to conceal his actions Throughout a year in the
• 0:22
  nineteen seventies, he discarded the remains of four young women
• 0:27
  at various locations along a roadway, in a gravel ditch,
• 0:32
  and beneath an underpass just outside Calgary in Western Canada.
• 0:37
  The victims were fully clothed, all had been strangled, and
• 0:41
  DNA analysis indicated that they had suffered sexual assault. Despite
• 0:47
  this evidence, it took nearly five decades and the examination
• 0:51
  of eight hundred fifty three potential suspects for Canadian law
• 0:55
  enforcement to disclose on Friday that these women had fallen
• 1:00
  prey to a serial killer. The perpetrator was identified as
• 1:05
  Gary Allen Serreri, who had escaped to Canada while on
• 1:08
  bail in nineteen seventy four after being charged with rape
• 1:13
  in Los Angeles. He passed away at the age of
• 1:16
  sixty eight due to natural causes in an Idaho prison
• 1:20
  in twenty eleven, where he was serving a life sentence
• 1:24
  for a rape committed in that state. Authorities suspect that
• 1:29
  he may have been responsible for the deaths of additional
• 1:32
  women in both Canada and the United States. Despite mister
• 1:37
  Serreri's audacity, there were limited witnesses to the murders, which
• 1:41
  took place in nineteen seventy six and nineteen seventy seven.
• 1:46
  The investigation extended over several decades. In the nineteen nineties,
• 1:52
  four distinct task forces meticulously examined leads, which included approximately
• 1:58
  eight hundred tips and five hundred public statements. As noted
• 2:02
  by Soup David Hall of the Royal Canadian Mounted Police
• 2:06
  during a news conference in Edmonton on Friday, no investigation,
• 2:12
  no matter how successful, could undo the harm caused by
• 2:16
  crimes of this nature, Superintendent Hall said, but he added
• 2:21
  the perseverance of investigators over many years allows us to
• 2:25
  bring answers to the families of the four young women
• 2:28
  robbed of their futures. Three of the four victims were adolescents.
• 2:34
  On February fifteenth, nineteen seventy six. Ever, de Vorak and
• 2:39
  Patricia McQueen, both age fourteen, were visiting friends after school
• 2:44
  and were last seen together around midnight. Their bodies were
• 2:48
  discovered less than twelve hours later in an underpass. Seven
• 2:52
  months later, the body of Melissa Riehorek, a twenty year
• 2:56
  old hotel housekeeper, was located in a gravel day which
• 3:00
  just west of Calgary, one day after she had been
• 3:04
  reported missing. Prior to her disappearance, Miss Rahorek had informed
• 3:09
  her roommate. Five months later, authorities found Barbara McLean, a
• 3:15
  nineteen year old bank employee who had gone out with
• 3:18
  friends to a cabaret show at a bar in Calgary.
• 3:22
  Witnesses last observed her walking home from the bar in
• 3:26
  the early hours of February twenty sixth, nineteen seventy. A
• 3:32
  dog walker discovered her remains, which exhibited signs of a
• 3:36
  struggle against her assailant. According to police reports, seamen was
• 3:41
  detected on all four victims. However, at that time, the
• 3:47
  investigative methods available for analysis were limited. It was not
• 3:52
  until two thousand and three that laboratory tests could connect
• 3:55
  the same unidentified perpetrator to the DNA sample found on
• 4:01
  two of the victims. Mis Rahoric and Miss McLain. A
• 4:05
  significant breakthrough in the case occurred through the application of
• 4:09
  genetic genealogy, a forensic method that utilizes DNA samples to
• 4:14
  identify relatives of a suspect. In twenty twenty two, DNA
• 4:20
  from the murders of Misdvorak and Miss McQueen was employed
• 4:24
  to link all four homicides to the same individual, mister Soreri.
• 4:30
  By the time mister Schrerie arrived in Canada in the
• 4:33
  mid nineteen seventies, he was already a convicted rapist. In
• 4:37
  the United States, investigators are currently assembling a comprehensive timeline
• 4:43
  of mister Serrairi's life, tracking his activities from nineteen seventy
• 4:48
  nine to nineteen ninety eight. His nomadic lifestyle, the nine
• 4:53
  aliases he adopted, and his history of violence lead authorities
• 4:57
  to believe that he may have been involved in additional homicides.
• 5:02
  We firmly believe that the suspect is not limited to
• 5:05
  just four murders. There is a significant likelihood that he
• 5:09
  is linked to many more, potentially in Alberta, British Columbia,
• 5:14
  or the Western United States, stated Staff Sergeant Travis Mackenzie,
• 5:19
  a commander with the Mounty's Historical Homicide Unit during a
• 5:23
  press briefing. Although mister Shrerie was never interrogated regarding the
• 5:28
  Calgary murders, he was convicted in Canada for a separate
• 5:32
  rape case in nineteen ninety eight in New Westminster, British Columbia,
• 5:37
  and was subsequently deported to the United States in two
• 5:40
  thousand three. In light of mister Cerreiri's death, the police
• 5:45
  have presented a thorough account of their findings to the
• 5:48
  victim's relatives, explaining the rationale behind their focus on mister Seriri,
• 5:54
  as noted by staff Sergeant Mackenzie in an interview, I
• 5:59
  am aware that they are thankful and appreciative, he remarked,
• 6:03
  but I also recognize that their grief has persisted without interruption.
• 6:09
  Mister Srerie was born in Oak Park, an affluent suburb
• 6:13
  of Chicago, before relocating to California with his family and
• 6:17
  three younger siblings.
