Less than two hours later, different officers responded to the same home and found Wells dead at the base of a stairwell, authorities said. The New York Post reported officers were dispatched to check on the young mother who was "scared" of her husband because he was "acting amusing".
Meanwhile, officials confirmed Thursday that Internal Affairs is investigating the police response to a call for a wellness check at the home earlier that day.
According to the New York Post, police received a call from the sister of 22-year-old Tonie Wells, who was concerned about the safety of her sibling, whose husband may have been putting her in considerable danger.
While officers were dispatched to the Wells' Crown Heights residence, they didn't even get out of their vehicle to check on the woman, law enforcement sources told the Post. Police said she had bruising on her neck and other signs of trauma.
The detained man is not the father of Wells' 2-year-old, according to family members.

"These cops completely sh*tcanned the job", a New York Post source said.
"They didn't even go up to the house", a neighbor reportedly said. The husband was identified by police as a person of interest and was in custody for questioning, WPIX-TV reported.
Investigators are treating the death as a possible homicide, Deputy Chief Michael Kemper, Commanding Officer of Detective Borough Brooklyn North told reporters. Police officials are also looking into whether the 911 dispatcher gave the officers complete information about the incident. The medical examiner will determine Wells' cause of death.
