Relatives of Rachel Morin are convinced that her killer has more victims due to “time gaps” in the USA

The sister of murdered mother Rachel Morin of Maryland told the Washington Post on Monday that the family fears her attacker, an illegal immigrant, could be a serial killer who has murdered other victims while in the United States.

Victor Antonio Martinez-Hernandez, 23, an accused Salvadoran gang member, was arrested Friday for the brutal rape and murder of 37-year-old Rachel Morin on a hiking trail in Harford County, Maryland, in August. He was already wanted at the time for an earlier murder in El Salvador and the attack on a mother and her little girl in Los Angeles.

“We are concerned that there are other victims … whether they were attacked and it ended up the same way my sister did, or whether there are others who are still alive but never came forward,” said Rebekah Morin, 43. “Hopefully they will come forward now.”

Rebekah noted that there was a gap of months between his known crimes in the United States.

“There was a long time between his last victims and Rachel’s attack,” Rebekah said.

“Someone who commits this kind of crime does it because he doesn't care. He doesn't think about what he's doing, and a person who doesn't care about human life can easily do something like that to anyone who crosses his path.”

According to police, Martinez-Hernandez has been living illegally in the United States since February 2023 – a month after he allegedly murdered a young woman in El Salvador.

Once in the United States, he attacked a nine-year-old girl and her mother in a brutal break-in at their Los Angeles home on March 26, authorities said.

In August, he struck again, killing Morin. Martinez-Hernandez was charged with first-degree murder and rape.

“Our Baltimore Genetic Genealogy Investigation Team spent countless hours identifying the suspect using DNA from the crime scene and tracing that DNA to possible family members,” said Bill DelBango of the FBI's Baltimore Field Office.

“Investigators have even traveled to El Salvador as part of their efforts to identify this killer,” he said. “To find the suspect, we have provided technical support to determine his whereabouts. This brings us to [Friday night]where Tulsa Police and FBI agents were able to apprehend and detain the suspect in Oklahoma.”

Rebekah said her family was notified of the warrant shortly before Martinez-Hernandez was arrested. She said Rachel's five children — ages 8 to 18 — were also notified.

“Some are much younger than others, and it's hard to fully understand how they're feeling or if they fully understand what this means,” she told The Post, adding that the children now live with their respective fathers.

The mother of five was abducted from the Ma and Pa hiking trail in Bel Air, Maryland, and dragged into the woods, authorities said. Her body was found in a sewer on August 6.

“It’s a relief to have a suspect in custody and to be able to put a name and a face to someone…” Rebekah said.

“But it also gets everything going again and makes you feel like it’s day one again.

“We want to ensure that the [killer] will never be able to walk on the streets again,” she said.

Randolph Rice, a lawyer representing the victim's family, told the Washington Post on Monday that he also believes Morin's killer “has other victims across the United States.”

“If you apply the law of probability and you murder someone in El Salvador in January, go to California in March and attack a mother and daughter, then there's a gap from March to August where he rapes and murders Rachel, and then another gap of 10 months until he's arrested … it's hard to imagine that he didn't commit another crime during those periods or gaps,” Rice said.

“[The Morin family is] fears that there are more victims.

“I also have no doubt that there are other victims. We hope that the arrest of this man will give them the courage to come forward because he can no longer harm them, otherwise they may see him and recognize him and be able to identify him,” Rice said.

Martinez-Hernandez is known to have spent time in Maryland, Virginia, Los Angeles and finally Tulsa, where he was arrested.

Authorities found the career criminal “sitting casually at the bar” on Friday evening, Tulsa police said in a Facebook post.

“We are 1,800 miles from the southern border here in Harford County,” Sheriff Jeffrey Gahler of Harford County, Maryland, said at a press conference Saturday.

“[This] should not happen. Victor Hernandez did not come here to give himself or his family a better life – he came here to escape a crime he committed in El Salvador.”

The extradition process to bring the Martinez-Hernandez to Maryland has already begun, said Harford County Attorney Alison Healy.

The immigration authorities ICE have also issued an arrest warrant for Hernandez because he is in the United States illegally, Gahler said.

“I'm here to tell you that Rachel's killer is no longer a free man,” Gahler said. “Hopefully he will never have the opportunity to walk free again.”
