An illegal migrant from El Salvador is responsible for the murder of Rachel Morin, a Maryland mother of five, police announced.

In a press conference on Saturday, Harford County Sheriff Jeffery Gahler said that Victor Martinez-Hernandez was arrested late Friday night and booked on Saturday morning.

"Five hours after meeting with [Morin's] family and just before midnight our time, police in Tulsa, Oklahoma assisted by our federal partners, located and arrested Rachel's murderer: Victor Antonio Martinez-Hernandez," Gahler said.

He was charged with first-degree murder and first-degree rape.

The 23-year-old migrant illegally crossed into the United States in February 2023, police announced.

"We all suspected that Rachel was not his first victim," Gahler said. "It is my understanding that this suspect, this monster, fled to the United States illegally after committing the brutal murder of a young woman in El Salvador a month earlier, in January of 2023."

Gahler said that their first DNA match for Martinez-Hernandez was from a Los Angeles attack in March 2023.

"Once in our country, and likely emboldened by his aminity, he brutally attacked a nine-year-old girl and her mother during a home invasion in March of 2023 in Los Angeles," Gahler said. "And as everyone I believe is aware, that was our first DNA match linking Rachel's case to the one in Los Angeles."

The sheriff turned his attention to the crisis at the Southern border, directing his remarks to the White House and to "both members of Congress."

"We are 1800 miles of the southern border," Gahler said. "And American citizens are not safe because of their failed immigration policies."

"This is the second time in two years that an innocent Harford County woman has lost her life to a criminal in our country illegally," he said, repeating his statement. "In both cases, they are suspects from El Salvador with ties to criminal gangs. This should not be happening."

"Victor Hernandez did not come to this country to make a better life for him or his family, he came here to escape the crimes he committed in El Salvador. He came here to murder Rachel and God-willing, no one else," he said.

"But that should have never been allowed to happen," Gahler said.

Morin, 37, was reported missing in August by her boyfriend, who said she never returned after going out for a run on the Ma & Pa Trail, a pedestrian trail in Bel Air, a quiet and typically safe town about 28 miles northeast of Baltimore, Aug. 5, 2023.

Her body was found on a trail the following day.

In February, police released new sketches of, now identified, Martinez-Hernandez.

The sketches came after DNA evidence linked Martinez-Hernandez to the scene of a Los Angeles, California home invasion.

Police used the Combined DNA Index System (CODIS), which led them to a single DNA match for an unidentified Hispanic male.

The Los Angeles Police Department (LAPD) collected a hat left behind at the scene of the March 2023 home invasion that turned violent, leaving multiple people, including minor children, injured. 

The suspect allegedly broke into the home in the middle of the night and assaulted the family inside before he was chased out. Surveillance video footage captured the man leaving, shirtless, through the front door.

"I'm going to make this short because I'm very emotional," Rachel's mother, Patricia Morin, said. "I just want to take this time to thank all the law enforcement for all their hard work."

"They just really cared for our family and for our daughter," she said. "They were going to diligently work and find the person who murdered her."

Former President Obama on Saturday marked 12 years since his executive action on the Deferred Action for Childhood Arrivals program, or "DACA," and called on Congress to codify the program into law before it expires. 

The Obama administration implemented DACA in 2012, so that those who entered the U.S. illegally as children were protected from deportation and had a pathway to citizenship. 

Recipients, called "Dreamers," were able to request "consideration of deferred action" for a period of two years, which was subject to renewal.

"Today, most of the original Dreamers are grown. They’re serving their communities as teachers, doctors, lawyers, and having children of their own. But because the program that offered that protection remains temporary, they’re also living in fear of being sent back to a country many of them can’t even remember," Obama said in a post on X. 

Obama praised the Biden administration for making it easier for Dreamers to access federal programs like health care. But he warned that Dreamers will "continue to live under a cloud of uncertainty" until Congress acts. 

"That’s why I’m calling on Congress once again to pass a permanent legislative solution for Dreamers — one that offers them a pathway to citizenship and makes our immigration system fairer, more efficient, and more just," Obama said. 

President Biden will host a White House event next week celebrating the Obama-era initiative as his own administration prepares potential new benefits for other illegal immigrants who have long-standing ties in the U.S.

Five people with knowledge of the plan told The Associated Press that White House officials are closing in on a plan that would tap the president’s executive powers to shield spouses of U.S. citizens without legal status from deportation, offer them work permits and ease their path toward permanent residency and eventually American citizenship.

Still, the timeline for implementing that plan, if at all, remains unclear. 

To protect the spouses of Americans, the administration is expected to use a process called "parole-in-place." It not only offers deportation protections and work permits to qualifying immigrants but also removes a legal obstacle that prevents them from getting on a path to a green card, and eventually, U.S. citizenship.

That power has already been used by other groups of immigrants, such as members of the U.S. military or their family members who lack legal status.
