A Washington state man was shot and killed by a neighbor after allegedly opening fire on two women during a domestic dispute that spilled into a nearby driveway, police said.

Officers with the Puyallup Police Department (PPD) responded around 9:10 a.m. April 2, when investigators allege 47-year-old Arnino Guanlao shot two adult female relatives after a family argument escalated outside the home.

A neighbor, who had been inside at the time, went outside and intervened, fatally shooting Guanlao, according to police.

One of the victims, 23-year-old Christiannel Lyle Macapagal Maningat, died at the scene. The second woman was transported to a hospital with life-threatening injuries, authorities said.

Authorities said the case remains under investigation, including a review of the neighbor’s use of force.

Washington law allows a person to use force to protect himself or others if he reasonably believes it is necessary, but deadly force is only justified when facing an immediate threat of serious injury or death.

“That’s under investigation as to exactly how the circumstances took place,” PPD Capt. Kevin Gill said during a press briefing.

Witnesses described a chaotic scene as gunfire erupted in the neighborhood.

“There was a girl here who was face down, and she was still breathing a little and trying to move a little, but she wasn’t doing much. And then pretty quick a cop came on scene, and he and I pulled her out, turned her over and found her gunshot wound on her abdomen,” neighbor Michelle Weingarden-Bandes told FOX 13 Seattle.

“We are all not just in shock about what we saw, those of us who were out here this morning, but that this has happened in our neighborhood.”

Investigators said the neighbor who shot the suspect is cooperating as detectives work to determine the circumstances of the use of force, according to FOX 13 Seattle.

Detectives are also working to determine what led to the dispute and are processing multiple sites linked to the incident, the outlet reported.

Residents reported hearing multiple gunshots during the incident.

Law enforcement officials said detectives are continuing to interview witnesses, many of whom were left distraught by the violence.

Additional reporting by Law & Crime identified Guanlao as the victims’ stepfather and said he had been firing at his adult stepdaughters when the neighbor intervened.

Authorities have not said what sparked the initial dispute.

The PPD said detectives with its Criminal Investigations Division, along with the Metro Cities Crime Response Unit, are continuing to investigate the incident.

Fox News Digital has reached out to police for additional information.

The violence has left the victims’ family reeling.

A GoFundMe created for the family says the victims’ mother is now caring for her surviving daughters while grieving the loss of one child and remaining at the bedside of another who is still hospitalized.

The fundraiser, which has raised nearly $19,000, says the family’s lives “changed in a matter of moments” and describes the emotional toll on the two other daughters now coping with the aftermath of the violence.

Organizers said the funds will help cover funeral costs, medical expenses and basic living needs as the family navigates the aftermath of the shooting.

A New York City man is facing murder charges after allegedly randomly setting a fire in a Queens apartment building that killed four people, including a 3-year-old girl, and injured seven others, authorities announced.

Roman Amatitla, 38, of Maspeth, was arrested Wednesday and arraigned on multiple charges, including eight counts of second-degree murder and first-degree arson, for the March 16 blaze at a three-story building in Flushing. 

He faces up to 25 years to life in prison if convicted.

Queens District Attorney Melinda Katz called the incident an “act of mass murder,” noting Amatitla’s chilling lack of motive.

“Shockingly, the defendant had no known connection to the building or any of its occupants and selected the building at random,” Katz wrote in a statement.

According to prosecutors, Amatitla entered and exited the Avery Avenue building multiple times late that morning, at one point urinating in front of the apartments. 

He then went to a nearby gas station, where he bought a beer, stole a second one and took a pack of matches after refusing to pay for a lighter, authorities allege.

He then entered the apartment building for a fourth and final time, authorities said, allegedly lighting a piece of paper on fire and tossing it onto trash near a stairwell. 

As smoke engulfed the street, he stayed in the immediate area to watch the building burn.

During a court hearing Thursday, Queens Assistant District Attorney Gabriel Reale said Amatitla “watched as people jumped from various windows, some of them living, one of them dying” while sipping on a beer, according to a report from the New York Post.

Three of the people killed in the blaze, identified as Sihan Yang, 3, Chengri Cui, 49, and Chie Shin Ming, 61, were found in the building and pronounced dead from smoke inhalation. 

A fourth victim, Hong Zhao, 64, died at a hospital after suffering multiple broken bones and brain trauma when he leaped from a window to escape the flames.

Among those injured were a New York City Fire Department (FDNY) lieutenant and a firefighter who plunged into the basement when a staircase collapsed during rescue operations, resulting in thermal burns and smoke inhalation.

Four other occupants were injured jumping from the building to flee the fire, while a fifth was rescued from a second-story window by firefighters.

Prosecutors said Amatitla “had to get his rage out on someone or something,” though no official motive has been released.

New York City Police Department records note he is from Mexico, though his immigration status has not been confirmed.

The Department of Homeland Security and Immigration and Customs Enforcement did not immediately respond to inquiries from Fox News Digital.

Amatitla was ordered to remain in custody by Criminal Court Judge Thomas Wright-Fernandez and is scheduled to return to court April 13.

Philadelphia residents have been sharing sidewalks with robot delivery drivers for about a month, and they’re not thrilled with the change. Uber Eats held a demo March 10 showing off Avride autonomous delivery robots, which officially launched in the city of brotherly love that same week.

The robots were described as “the future of delivery,” but the humans around them quickly began resenting the automated couriers. In late March, an Uber Eats delivery robot in Philadelphia’s Center City neighborhood was kicked multiple times. 

The second time the autonomous delivery bot was kicked it toppled over, according to WPVI-TV, which noted that the people who attacked the robot put it on its wheels. 

The kicking incident occurred just after another viral incident in which someone sat on one of the robots.

THE ROBOTAXI PRICE WAR HAS STARTED. HERE’S EVERYTHING YOU NEED TO KNOW.

“When delivery robots are introduced in a new area, it’s quite common to see heightened curiosity from people around them. Some may try to ‘test’ how the robot reacts — for example, by stepping in front of it or attempting to interact with it directly,” Avride, the company that makes the robots, said in a statement provided to Fox News Digital.

“This is a known and expected phase as people get used to the technology. These few cases of vandalism in Philadelphia did not affect our service area expansion plans.

“The robots are designed to respond conservatively. In most cases, they will simply stop and wait if someone approaches or interferes, resuming their route only once the interaction has ended. In practice, these moments are usually brief — people tend to satisfy their curiosity within a minute or so and then move on. At the same time, we do not condone intentional damage or unsafe behavior toward the robots.”

Lindsay Ouellette, a third year PhD student in social psychology who is part of Temple University’s Robot Social Navigation Amongst Pedestrians (roboSNAP) team, told BillyPenn the frustration with the robots is not new, just aimed at a new target. She said that just as pedestrians can be frustrated with fellow humans who walk slowly or are looking at their phones, they can also take issue with the delivery robots.

The delivery robots have been deployed to dozens of cities across the U.S., including Austin, Dallas and Jersey City. The robots keep the orders secure by requiring customers to unlock the cargo hatch through the Uber Eats app. Additionally, Avride is immediately notified if someone tampers with or tries to steal the device.

“The cargo compartment of each delivery robot is securely locked and can only be opened by the intended recipient through a mobile app. If anyone attempts unauthorized access or tries to steal the robot, it triggers an alert to our remote operator. The operator will immediately connect to the robot’s sensory feed to evaluate the situation and take appropriate action to secure it,” Avride said on its website.

While the robots are able to navigate without human intervention, Avride has a remote support team that is able to control the robots in the case of “an extraordinary situation arises.”

The robotic delivery service is available from 10 a.m. to 10 p.m. in the Philadelphia neighborhoods of Center City, Chinatown and Old City. The robots use LIDAR sensors and cameras to navigate and are able to travel about 5 miles per hour.

Avride says its robots are able to operate in a variety of weather conditions, including rain and snow. Additionally, the company said its bots can interpret and recognize traffic light signals, giving them the ability to safely navigate busy city streets.

While customers have shown skepticism, business owners see robot delivery as an opportunity.

“I think more ability to deliver food is better for us,” Jeff Newman, owner of Hi-Lo Taco Company told WTXF-TV. 

“And certainly, right now, it started raining, and we see that we have a higher demand for takeout and delivery, but we also have fewer drivers.”

Uber forwarded Fox News Digital’s request for comment to Avride.
