UVALDE, Texas — The mother of the gunman who killed 21 people at an elementary school in Uvalde, Texas says she wants people to forgive him.

“I have no words. I have no words to say. I don't know what he was thinking. He had his reasons for doing what he did and please don't judge him. I only want the innocent children who died to forgive me,” Adriana Martínez told reporters from Mexico.

Martínez said she believes her son had his “reasons” for the shooting.

“What reasons could he have had?” a Televisa reporter asked.

“To get closer to those children, instead of paying attention to the other bad things. I have no words, I don't know,” Martínez said.

Investigators say the gunman shot his grandmother at home before going to Robb Elementary School.

She survived and is still in the hospital.

This story was first reported by KTNV in Las Vegas.

BRIDGEWATER, Va. (AP) — Two officers were shot and killed at a private Virginia college and a man believed to be the shooter was taken into custody.

Bridgewater College issued a statement Tuesday evening saying police had apprehended a suspect after searching the campus.

The school told students in a tweet at around 2 p.m. that a suspect was in custody but that they should shelter in place.

The school sounded the all-clear about 4:30 p.m.

The officers were identified as Campus Police Officer John Painter and Campus Safety Officer J.J. Jefferson.

Authorities did not discuss a possible motive for the shooting.

Bridgewater College is located about an hour's drive northwest of Charlottesville.

The school describes itself as a "private liberal arts college" that was founded in 1880. The school says it has an enrollment of about 1,800 students.

A psychology professor is trying to understand real-world implications of potential misperceptions people wielding a gun could have.

“One of the reasons why unarmed people get shot might be that the people who are holding the gun literally misperceive that other person – the victim – as having a gun,” psychology professor Dr. Jessica Witt said.

Dr. Witt is a professor of psychology at Colorado State University. For more than a decade, she’s been researching how the mind can be impacted by holding a gun.

“What happens when you hold a gun?" Dr. Witt said. "What are the implications of holding a gun? How does that change how you see the world?”

To try and answer these questions, Dr. Witt's team collected videos and photos of people in different locations either holding a gun or holding a shoe.

“For each image that you see, you need to decide whether the person in the image is holding a gun or holding a shoe," Dr. Witt said. "If you see them holding a gun, you are to raise your hand and whatever object you’re holding and point to the screen. And if you see a shoe, you are to lower your arm and point to the ground. And what we did that was unique from previous research, was that we systematically manipulated whether the participant was also holding a gun or holding a neutral object.”

A neutral object like a spatula – using motion-tracking technologies. Dr. Witt says the idea is that holding a gun – which she says turns them into shooters – could change their ability to act. She wanted to find how these images look to shooters compared to when they’re holding a spatula.

“One of the metrics we looked at was their accuracy," Dr. Witt said. "And we found that when they saw a gun, they said it was a gun about 98% of the time so they were really good at detecting a gun when it was there. The question was, when they saw a shoe, what did they do? In that case, performance was still pretty high but not as high. So when they were holding a neutral object like a spatula, they said it was a shoe 93% of the time. But when they held a gun and they saw a shoe, that’s when we saw the most errors. So they had the hardest time identifying when the other person was not holding a gun when they also held a gun.”

Dr. Witt says they also found a similar pattern with reaction time. Reaction time took the longest when a participant saw a shoe and was holding a gun.

“So it was as if holding a gun made their visual system make them want to see a gun there and they had to inhibit that response which took time and resulted in slower responses," Dr. Witt said. "And if they didn’t inhibit that it then resulted in more errors.”

Jacob Paulsen is the president of concealedcarry.com. He’s been a firearm instructor for 13 years.

“Concealedcarry.com is a national resource for American gun owners who feel compelled to defend themselves and their loved ones from violent threats,” Paulsen said.

After reading about the study, he agrees the topic is worthy of research.

“It’s believable that someone who’s carrying around a gun might be more likely to infer that when they face a dangerous situation -- that the person that they’re facing might be holding a gun versus some other object," Paulsen said. "That would seem logical on the surface.”

However, in the study, the method was tested on university students. Paulsen says the study should be expanded to gun owners and people in gun-wielding jobs.

“If we want to draw some sort of conclusion based on what law enforcement is likely to find based on some sort of cognitive bias, then it would make sense to conduct the research with law enforcement officers," Paulsen said. "Similarly, if we’re trying to determine if the average concealed carrier out there walking around with a concealed gun whether they are experiencing some sort of cognitive bias, then the research should probably be conducted with that consumer group.”

Dr. Witt says she also wants to expand the study. In fact, she has a grant under review with the National Science Foundation. Her goal is to understand if some people are more protected from these errors and if others are more prone to them. With more data, perhaps training programs and hiring practices could be developed to prevent the errors. As a gun owner himself, Paulsen says training is super important.

“We need to remember that the second amendment of our constitution gives us the right to keep and bear arms as a citizenry," Paulsen said. "However, with all rights comes a certain degree of responsibility so the onus is on us – the gun owners – to seek out and receive as much training as we practically and conceivably can in order to minimize potential risks that also come with gun ownership.”

CNN —

Eric Talley, the first police officer to arrive at the scene of the Boulder supermarket shooting last week, was the last of the gunman's 10 victims.

To honor his bravery, the nonprofit Tunnel to Towers Foundation, set up to support the families of fallen first responders and service members, announced Saturday it will pay off the mortgage on Talley's home.

Talley, 51, is survived by his wife and seven children.

The community came together to grieve him

Hundreds flooded the streets in the days after Talley's death, watching as a hearse transferred his body to an Aurora funeral home.

His patrol vehicle, parked in front of the police station, was adorned with flowers, cards and other tokens of grief and gratitude.

Talley was the first Boulder officer to be killed in the line of duty since 1994, and the sixth on-duty death in the department's history, according to the National Law Enforcement Officers Memorial Fund.

His bravery was known to his friends and colleagues well before his death.

"Didn't surprise me he was the first one there," his father, Homer Talley, told CNN affiliate KUSA.

Talley had been a member of the Boulder police force since 2010.

He was aware of the danger he faced as a police officer. His father told KUSA he recently looked into becoming a drone operator because he thought it would be safer.

Police Chief Maris Herold said at a news conference that Talley was "willing to die to protect others" and embodied "everything policing deserves and needs."

Within 30 seconds of arriving at the King Soopers store, Talley led a team of officers inside to engage the shooter, the Boulder Police Department wrote in a tweet. After Talley, no one else was shot.

A non-profit for first responders is responding to Talley's death

The Tunnel to Towers Foundation was created in honor of New York firefighter Stephen Siller, who died responding to the 9/11 terrorist attacks.

The organization builds mortgage-free smart homes for catastrophically injured veterans and first responders, and pays off the mortgages of first responders and military servicemembers who are killed in the line of duty and leave behind young children.

The foundation also provides mortgage-free homes to surviving military spouses with young children.

The nonprofit's mission to honor fallen first responders prompted the effort to pay Talley's mortgage.

"It's so important because Eric gave his life and left behind a wife and seven children, and for him to rush in and go toward ... the danger to save people is just incredible," foundation CEO Frank Siller, Stephen Siller's brother, told "Fox & Friends" on Saturday.
