Plano woman shot ex-husband after finding him on the phone with 'illegal woman,' affidavit says
PLANO, Texas - An arrest affidavit obtained by FOX 4 revealed more details about a Plano shooting involving a woman and her ex-husband.
Merridith Nunley, 38, is charged with the murder of her ex-husband, 55-year-old David Nunley.
Plano police received a 911 call on Friday night from David Nunley saying, "I've been shot."
Officers arrived at the home on Monticello Circle to find David in the garage shot in the chest with a cell phone nearby but no weapons, according to the affidavit.
While police searched the home, a family friend called 911 and told police she had received a call from Merridith, who said she had shot David.

The friend told police the Nunleys were divorced but were "still kind of living together."
Merridith allegedly told the friend she had shot David because she had found him on the phone with another woman, according to the documents.
Police were able to ping Merridith's phone and found her parked in an apartment parking lot on West Park Boulevard.
"They used the drone to initially look at the vehicle and see who was in there and then made phone calls. That way, they could talk with her," explained Plano Police Officer Jennifer Chapman.
Officers approached the vehicle and asked what had happened that night.
"David lost his temper, and he got physical with me, and I defended myself," she replied, according to the affidavit.
The affidavit said Merridith told officers she was "just in a trance" when she shot her ex-husband and asked police if he was okay. She eventually surrendered to police.
The report states the gun Merridith used to kill David was on the passenger seat.
After her arrest, Merridith told police she shot David after finding out he was talking to an "illegal woman," according to the affidavit.
Court records show David filed for divorce, and it was finalized in 2022.
Both parties had joint custody of their three kids at the time of divorce.

The friend who called police Friday night said the Nunleys had been living together.
Police also noted that the home had a history of calls for service involving disturbances and child abuse.
Brittany Mariscal lives in the neighborhood. She saw the Nunleys together recently.
"We've seen them come and go. We saw them on Easter Sunday going to church together, obviously with their kids," she said. "I heard from other neighbors that you could just hear them yelling at each other. Nothing good. It's just sad really sad. I think it's heartbreaking, and you never know what's going on inside somebody's house."
Police say the children were not home at the time of the shooting.
Merridith is being held at the Collin County Jail on a $500,000 bond.
