A York City man threatened his ex-partner twice last month before he shot her and her son in her home shortly before Christmas, police allege.

Isaac Newton Ramos-Perez, 44, is facing charges of two counts of attempted homicide, two counts of aggravated assault and a count of illegal possession of a firearm in the case. Ramos-Perez remains at large, and York City Police say he is armed and dangerous.

He is accused of shooting Yocasta Guzman Beltran, 44, and Jasell Custa, 26, seriously injuring them both, during a confrontation in a home in the 400 block of West Philadelphia Street on Dec. 23, York City Police said in charging documents.

The scene after a shooting on the 400 block of W. Philadelphia St. in York on Friday Dec. 23, 2022.

Investigators found four bullet shell casings at the scene, police said.

Leading up to the shooting, Ramos-Perez allegedly threatened Guzman Beltran at the home two other times in December.

He was charged in both incidents after Guzman Beltran reported them to police.

The first time, police said, he allegedly forced Guzman Beltran out of her home at knifepoint on Dec. 5.

That led to the filing of misdemeanor charges of making terroristic threats and simple assault and a summary offense of harassment against Ramos-Perez.

He apparently wasn’t arrested then. A warrant was issued, police said in the criminal complaint.

Ramos-Perez went back to the house Dec. 20, pulled a gun on Guzman Beltran while she was outside, and forced her back in, according to allegations in her second report. He allegedly told her he knew that she had called police to make the first report and that he was wanted, the complaint shows.

He was later charged with misdemeanor counts of stalking and simple assault in that incident.

Three days later, Ramos-Perez allegedly returned and may have broken into the house.

Investigators found a pry bar and a screwdriver near an open window out back, the complaint shows.

Guzman Beltran told police she was in a bathroom when she heard a commotion. She walked out, and Ramos-Perez allegedly threatened her with a gun, police said.

He tried to force her into the basement, but her son, Custa, told him to get out of the house and that he was calling police, according to the complaint.

Another person in the house heard Custa yelling “Newton, stop,” referring to Ramos-Perez’s middle name, the complaint shows.

Then the person heard gunfire, police said.

Ramos-Perez allegedly fled.

York City police released an image of a gray 2004 Ford F-150 as part of an investigation into the shooting of two people on Dec. 23.

Shortly after the shooting, police put out a call for tips in finding him. They said he was seen driving from the scene in a gray 2004 Ford F-150 with a Pennsylvania license plate number of ZTB-1252. He is considered armed and dangerous, police said.
