MCKINNEY, Texas - A McKinney man is behind bars after allegedly choking his pregnant wife to death.
According to court documents, the two weren't supposed to be in the same room together.
Police were called to an apartment on Collin McKinney Parkway on Christmas Day to perform a welfare check.
McKinney police said they received a call from an uncle of 33-year-old Nasib Ahsan, who claimed he had told a family member that he had killed his wife, Nawreen Tuli. They also advised police that there was a history of domestic violence at the location.
Police arrived at the apartment complex and contacted Ahsan, who told them Tuli was sleeping inside.
Officers then discovered Tuli dead inside, according to police documents. Ahsan was arrested at the scene without an incident.
Further investigation by police found that Ahsan had called his uncle earlier that day. Ahsan told the uncle that he had gotten home from work and began fighting with Tuli, according to an arrest affidavit.
Ahsan claimed that Tuli had choked him and that he responded by choking her to death, police documents show.
Police investigation showed Tuli's injuries were consistent with strangulation.

Ashan wasn’t even supposed to be in the same room as Tuli. In November, he was arrested for allegedly assaulting her.
Tuli’s niece, Tasneem Kabir, says she filed a protective order against Ahsan. But because of the baby, Tuli wanted to give him a second chance.
"She called my mom when her husband got arrested, and she was shaking with fear. So my mom told her to talk to someone there," Kabir said. "She always wanted to have a family, and that’s why she thought maybe he will get better, but eventually he didn’t."
Kabir hopes her aunt’s story is an example to others and encourages them to speak up before it’s too late.
"She was always an independent woman, but I don’t know what happened that she just accepted everything," she said. "I want him to pay for what he has done. I want him to be an example that no one can do that to anyone."

Tuli was just starting to make a life in the U.S. She moved here last year, leaving behind her family in Bangladesh.
Police documents say that Tuli was two months pregnant at the time of the November assault. An autopsy confirmed that she was pregnant.
Ahsan has been charged with capital murder. His bond is set at $1 million.
