The Supreme Court has denied Remington Arms Co.'s bid to block a lawsuit filed by families of victims of the Sandy Hook school massacre. The families say Remington should be held liable, as the maker and promoter of the AR-15-style rifle used in the 2012 killings.

The FBI has joined an investigation into the killing of three women and six children last week along a mountain road in northwest Mexico, an ambush that has shaken the Mormon community that has lived near the border for decades.

Federal investigators said the Mexican government, which is leading the probe, asked for the assistance of the FBI in examining the deaths of the dual Mexican and U.S. citizens.

Mass shootings, health care concerns and the upcoming 2020 presidential election top the list of Americans' worries these days. That's according to a new survey out this week from the American Psychological Association.

Overall, 71% said mass shootings were a significant source of stress in their lives, up from 62% last year. Hispanic adults were most likely to report stress over mass shootings (84%).

Several members of the extended family of Mormons whose relatives were attacked in northern Mexico on Monday are speaking out, saying it's time to reject gang violence. As family members prepare to bury the nine victims killed in that attack, they also say both the U.S. and Mexico should be part of the solution.

Federal prosecutors announced in August that they will pursue the death penalty against the man accused of killing 11 people at the Tree of Life synagogue last October. They argued in a court filing that one reason the attack was especially nefarious was because it stemmed from the defendant's hatred for Jews.

A state Senate committee in Florida is recommending the full Senate uphold the governor's suspension of former Broward County Sheriff Scott Israel. Gov. Ron DeSantis suspended Israel shortly after taking office in January, fulfilling a promise made during the election campaign.

The percentage of Americans who favor stricter gun laws is on the rise, though significant partisan divisions persist. A Pew Research Center survey conducted in September found that 60% of Americans say gun laws should be tougher, up from 57% last year and 52% in 2017.

The interim chief of the Fort Worth Police Department apologized on Tuesday to the family of Atatiana Jefferson in the aftermath of her fatal shooting by a police officer while she was in her home.

"This incident has eroded the trust that we have built with our community and we must now work even harder to ensure that trust is restored," said Interim Police Chief Ed Kraus.

A white police officer fired through the window of a black woman's home early Saturday and killed her after responding to a call that a neighbor placed about an open front door, authorities in Fort Worth, Texas, say.

Around 2:25 a.m., officers responded to an "open structure call" made by a neighbor to the police department's nonemergency number. Inside the home, Atatiana Jefferson, 28, and her 8-year-old nephew were playing video games.

More than two months after the carnage of the mass shooting at an El Paso Walmart, victims and immediate family members of those involved in the massacre can now apply for financial assistance from the fund that has drawn millions of dollars in donations.

One Fund El Paso, the group that has raised more than $6 million since the Aug. 3 shooting, is hosting a community resource fair on Saturday to help those who may qualify to navigate the application process.
