Mya Renee Migneault, 4

Mya Renee Migneault, a 4-year-old black girl, died Friday, March 21, after she suffered blunt force abdominal trauma in the 500 block of South Westlake Avenue in Westlake, according to Los Angeles County coroner’s records.

After Mya became unresponsive, her babysitter took her to a hospital on a bus.

Mya was pronounced dead at a hospital at 8:03 p.m., according to coroner's records. An autopsy showed that Mya died of blunt abdominal trauma, according to coroner’s records.

The girl's babysitter, Vanessa Denise Hawkins Scott, a 53-year-old black woman, has been charged with murder, assault on a child causing death, and child abuse, according to the Los Angeles County district attorney's office.

Mya's mother was out of state during the incident, and had "no hand in this," said police Lt. Craig Herron.

According to relatives, the girl's mother was with her fiance in the South when she got news about her daughter.

"All I can tell you is that Mya was my whole life," said her grandfather, Gary Greenberg, 59, who lives in Texas. “She never did anything. She was a perfect angel.”

The 4-year-old loved "Mickey Mouse" and "Dora the Explorer," relatives said.

Hawkins Scott is due back in court April 7.
