A white police officer in Texas fatally shot a black woman inside her home after officers were called to do a welfare check, according to authorities.

Atatiana Koquice Jefferson, 28, of Fort Worth was killed by an unidentified police officer with the Fort Worth Police Department on Saturday morning.

62-year-old James Smith, Jefferson's neighbor, called the local non-emergency number after he noticed her front door was open and lights were on around 2.25am.

He knew Jefferson was supposed to be home with her 8-year-old nephew.

'I'm shaken. I'm mad. I'm upset. And I feel it's partly my fault,' Smith told the Fort Worth Star-Telegram.

'If I had never dialed the police department, she'd still be alive.'

Fifteen minutes after authorities arrived to the scene, Smith heard a gunshot and watched several officers rush Jefferson's home.

According to a statement from authorities, officers responded to Smith's call and arrived to the 1200 block of East Allen Avenue.

In police bodycam footage that has been released, the officer is seen walking around the perimeter of the home and looking through windows inside the residence.

Smith is heartbroken over Jefferson's death.

'It makes you not want to call the police department,' he told Fort Worth Star-Telegram.

'If you don't feel safe with the police department, then who do you feel safe with? Do you just ignore crime or ignore something that's not right?'

'They tell you, 'If you see something, say something. ...Well, if you do that and it costs somebody to lose their life, it makes you not want to do that. And that's sad.'

Community members are outraged over Jefferson's sudden death and are calling for action.

Pastor Michael Bell of the Greater St. Stephen First Church laid bare his criticisms of the police department statements, according to WFAA reporter Cleo Greene.

Bell said in the Twitter video: 'We're tied of police lying. Ain't no perceived threat unless it's black folk. Just our presence... are we the threat?'

'Let's tell it what it is,' one community member said in a separate video, 'she was massacred in her own house.'

'Don't let this rest... where we get all up in arms for about two or three weeks and we go back to business as usual.

'We are still being murdered by the police. Something has to be done and done right away.'

The investigation is ongoing.
