Sheriff’s deputies in Maryland shot and killed a man early Tuesday after officials said the man stabbed his parents, killing his father.

Frederick County Sheriff’s deputies responded to a report of a stabbing at a Frederick home just after 2 a.m, officials said in a news release.

A 911 caller reported that her brother was stabbing their parents, Sheriff Chuck Jenkins said at a news conference. Deputies found a woman with stab wounds at the home and a man was found down the street, Jenkins said.

When three additional deputies arrived, they encountered an armed man and fired their weapons, the sheriff’s office said in a news release. The man, who is believed to be the son of the two people who were stabbed, died on the scene, officials said.

The father died at a hospital and the mother was flown to Shock Trauma, but her injuries were deemed superficial, Jenkins said.

The shooting will be investigated by the Independent Investigative Division of the Attorney General’s Office, division spokesman Thomas Lester said. A knife was recovered at the scene and some of the incident was captured on body-worn camera, he said.

The deputies who fired their weapons are on paid administrative leave, sheriff's office spokesperson Todd Wivell said.

A New York City man has been arrested for manufacturing and possessing more than a dozen ghost guns after he shared an image of his 7-year-old son wielding two of the firearms, prosecutors say. 

Cory Davis, 41, is now facing multiple charges after New York City police officers recovered 14 of the privately assembled weapons in two of his apartments, including "10 semi-automatic pistols and two assault weapon-style pistols," according to the Manhattan District Attorney’s Office. 

"The allegations make it evident that by manufacturing these weapons, Davis put not only the public, but a child in serious peril," District Attorney Alvin Bragg said in a statement. "Using one’s child as a prop to showcase homemade, illegal weapons is inexcusable and extremely dangerous. The proliferation of ghost guns in our city cannot continue." 

Bragg’s office says "an investigation was prompted after Davis sent a photo of his 7-year-old son holding two firearms to family and friends" in a group chat, "which was then provided to law enforcement.

"In addition to the 14 firearms, investigators recovered 400 rounds of ammunition, a high-capacity magazine, and nearly two dozen other magazines, as well as tools and parts for constructing ghost guns," it added.

Davis has been charged with one count of criminal possession of a weapon in the first degree, 16 counts of criminal possession of a weapon in the second degree, three counts of criminal possession of a weapon in the third degree, and 14 counts of criminal possession of a firearm. 

"Stopping the proliferation of ghost guns is integral to the NYPD’s comprehensive strategy to keep these illegal weapons from harming our communities," Police Commissioner Keechant Sewell said in a statement. "These untraceable weapons shoot real bullets, hurt real New Yorkers, and cause real harm – and our fight against them will continue with vigor."

The attorney's office also said Davis, "has been purchasing gun parts and accessories from several different websites since June of 2020."

"His online purchasing history included training tools, simulators, and concealable holsters," the office added.
