PICTURED: Mentally ill mom-of-two, 23, who 'left her daughter, 5, to die in 101F Las Vegas bedroom with no air conditioning' and told police it was a "necessary sacrifice"

Disturbing new details have emerged in the case of the Las Vegas woman who was arrested last week for the death of her five-year-old daughter in an overheated room, including that the mother was overhead saying 'it was a necessary sacrifice' and 'I killed it.'

Kemaya Taylor, a 23-year-old mother of two, was taken into custody on June 28 and charged with open murder and child abuse after police preforming a welfare check discovered her eldest daughter dead inside a stifling room with no air conditioning.

Taylor's two-year-old daughter was found alive and handed over to Child Protective  Services.

Neighbors said that prior to her arrest, a disheveled-looking Taylor was observed smashing parked cars with rocks and muttering, ‘I'm son of Jacob. I killed it.'

Kemaya Taylor, 23, a mom-of-two from Las Vegas, has been charged with open murder and child abuse for the death of her 5-year-old daughter inside a stifling bedroom 

Police found Taylor's eldest child unresponsive inside a locked upstairs bedroom at this home on June 28 

According to Taylor's arrest report cited by the station KLAS, nearly two weeks before her arrest, a friend contacted the police and requested a welfare check after receiving a text message from Taylor that she perceived as 'a vague suicidal threat.'

Taylor was said to have texted her friend that she quit her job and told her to ‘watch out on the news.’

Officers with the Las Vegas Metro Police were dispatched to Taylor's residence but could not locate the woman or her daughters that day.

Then on June 28, police returned to the home in the 10200 block of Missouri Meadows Street after getting a 911 call about an incident and found the residence 'in complete disarray.' According to the report, Taylor 'was suffering from some sort of mental illness.'

After taking the woman into custody, police searched the home and encountered a locked bedroom door on the second floor. They kicked in the door and discovered Taylor's two daughters inside. The report stated that the two-year-old was alive and standing next to the bed, and her older sister was lying on the bed unresponsive.

One of the officers began CPR on the five-year-old until paramedics arrived on the scene and pronounced her dead.

The document stated that the air conditioning in the house was off and 'the temperature in the bedroom felt exponentially warmer than in the rest of the residence.'

The temperature inside the locked bedroom was measured at 101 degrees, with a humidifier working on the maximum setting.

While Taylor was seated in the back of a patrol car, she began making statements, unprompted, saying, 'It was a necessary sacrifice,' and begging to be taken to an 'insane asylum,' according to the report.

When interviewed by the police, Taylor’s neighbors said they overheard her say: 'I am the son of Jacob. I killed it.'

Taylor's landlord previously told the Las Vegas News-Journal that the woman had been struggling financially and claimed that she had no family to help her.

But relatives from Sacramento, California, have disputed Taylor's claims, telling the paper that she never reached out for help, or told anyone she was experiencing money problems.

Marisa Brown, the paternal grandmother of Taylor's children, said on her son’s behalf that Taylor 'had all the help that she needed.' 

Police were called to Taylor's rental home in the 10200 block of Missouri Meadows Street in Las Vegas on Monday, when temperatures reached 108 degrees  

Brown and Kandra Coleman, the children's aunt, said outside of court last week that Taylor had recently stopped communicating with her many relatives in Las Vegas and Sacramento, including her children’s father.

‘He would text her and say, “You know it’s Father’s Day. I wanna hear from my kids. I should be able to. They are my children,”’ Coleman said.

Taylor texted back ‘of course,’ but then the father never heard anything again from his children.

Brown said Taylor also ignored her numerous text messages offering her help.

‘She never said there was a problem,’ Coleman said. ‘If her rent needed to be paid, we would have paid it. If we had to come together and just take up a collection from everyone in the family, those babies would have had a roof over their heads regardless. There is no reason that this should happen.’ 

Taylor's landlord told Las Vegas Review-Journal that she heard from neighbors that the young mother was acting erratically two days before police arrived.

‘She had one of her babies in her arms in that heat with blankets covering her baby … in a fetal position,' recounted the landlord. ‘She got up and started smashing windows of cars around here.'

Neighbors were said to have observed Taylor walking with a bat and smashing a truck's windows with a KitchenAid mixer.

The landlord also revealed that Taylor struggled financially and failed to pay rent in June.

When the owner of the home came by to check on Taylor and her family in the weeks leading up to the tragedy, she said she found the woman in a state of disarray.

‘Her hair was all a mess, the whole house was a mess, and she was packing. That’s when I said, “You know, I think it is not good you are all by yourself with two kids. You should get in touch with your family,” and she said, “I have no one,”’ said the landlord.

Taylor was booked into the Clark County jail on a charge of open murder and two counts of child abuse.

Taylor is due in court for a preliminary hearing on July 15.
