A McKinney man is in jail after police found a woman’s body in a home Sunday morning.
According to the McKinney Police Department, detectives received a tip that a body may have been found at his home in the 600 block of Pearson Avenue.
Authorities said they obtained a search warrant and went to the home, where they found 42-year-old Chad Christopher Stevens.
“I woke up this morning and all I heard was helicopters and police telling someone on Pearson Ave. to come out with their hands out,” said Carolina Murillo, whose family woke up to the presence of McKinney police on their street.
“I was freaking out because this is supposed to be a quiet neighborhood, you know?” Murillo said.
He said officers blocked roads and a SWAT team gave orders to his neighbor who was inside the house across the street.
“Everyone says, ‘Oh my God.’ They are doing a lot of things. So, I can’t believe this happened. You know, we’ve been saying “Hi” or whatever. It’s scary,” said Murillo, who would also greet his neighbor over the years.
“I mean, we’ve lived here for the last few years. “So probably a few times, like every day after I got home from work, I said, ‘Hi,’ and that was all the interaction we had,” Murillo said.
A neighbor’s video showed the moment police arrested Stevens and also removed evidence from the home.
While executing the search warrant, detectives found the body of 35-year-old Heather Louise Schwab. Stevens was arrested at the scene and charged with tampering with evidence with intent to injure a human corpse.
“My parents and my brothers saw as if someone took like a refrigerator and also the neighbor. I also heard that they took out a black bag, like a body bag,” Murillo described.
In a news release sent to media, police said Schwab was missing, but a spokesperson could not confirm details Sunday.
“It could have been a different woman, but a few months ago, there was a woman like you know around him. She liked to follow him everywhere. I just did everything he did, but she was always around, and then a couple of months later, you know, I stopped seeing her and I was like, ‘Okay, well, maybe they broke up or whatever happened, and that.’ That’s how it was,” Murillo reflected.
He described Stevens as “uncomfortable” and always outside.
“He was at the top at all times. Like every time he left the house or came in, as if he was always outside. Just walking around doing things in the garden,” Murillo said.

The investigation is ongoing. Anyone with information about this case is asked to contact Detective Monte Robertson at 972-547-2724.
