An Oklahoma man who was doing target practice in his backyard on Christmas is believed to have shot and killed an elderly woman a few blocks from his home, authorities said.

Cody Wayne Adams, 33, has been charged with first-degree manslaughter in connection with the deadly shooting, court filings show. 

The victim was on a covered front porch with family members at a residence in Comanche when she was shot Thursday afternoon, according to the probable cause affidavit. She was holding a baby in her left arm while seated on a love seat when she was struck in her right upper arm, according to the affidavit. The bullet then entered her chest cavity, it said. 

First responders were dispatched to the residence at approximately 3:15 p.m. Thursday, the Stephens County Sheriff’s Office said. She was pronounced dead soon after, according to the affidavit. The sheriff’s office did not publicly release the name or age of the victim, describing her in a news release as an “elderly female.”  

The family members told a responding deputy they had heard someone shooting five to seven rounds over several minutes north of the residence, according to the affidavit. The victim “commented that someone got a new gun for Christmas” and then shortly after “said ‘ouch’ and collapsed,” according to the affidavit.

Law enforcement investigating the shooting canvassed several residences to the north of the deadly shooting and found that all but one — Adams’ — had “suitable shooting backstops or firing locations,” according to the affidavit. Deputies had also received information that Adams had received a Glock 45 for Christmas and that his neighbors had heard him shooting “about 20 rounds” Thursday afternoon, according to the affidavit.

Adams allegedly told deputies who responded to his home that he had been shooting a Glock 45 that he recently bought for himself for Christmas at a Red Bull can in his backyard, according to the affidavit. 

When a deputy said he suspected the shooting may have caused the victim’s death, Adams “became visibly upset and began to cry,” the affidavit stated. The deputy also told him that “while he was shooting towards the ground in his backyard that there was nothing behind his property to stop any bullets from traveling beyond his property and hurting someone,” the affidavit stated. Adams’ home is located approximately 0.3 miles away from the residence where the woman was shot, based on the addresses included in the affidavit.

After being read his Miranda rights, Adams allegedly acknowledged that he was shooting south from his residence on Thursday with the Glock handgun, which had been loaded with approximately eight and then 10 rounds of Winchester .45 caliber ammunition, according to the affidavit. 

Deputies arrested Adams on Thursday evening for first-degree manslaughter after consulting with the local district attorney’s office, the Stephens County Sheriff’s Office said.

The charging document alleges that he caused the woman’s death “by engaging in conduct with a firearm that created a situation of unreasonable risk and probability of death, or great bodily harm, to another person and demonstrated a conscious disregard for the safety of others.”

During his initial court appearance on Friday, Adams’ bond was set at $100,000, according to online court records. A preliminary hearing has been scheduled for Feb. 26. ABC News was unable to reach Adams or his attorney for comment.
