Taquesta Graham, 28, appeared briefly in the Los Angeles County Superior Court in Pomona. His indictment has been postponed until 16 April. She is currently held without bail at the Century Regional Detention Center in Lynwood, according to prison records.
We did not know if she had a lawyer.
Graham and his boyfriend, Emiel Hunt, 38, are accused of killing Trinity Love Jones on March 1, according to a criminal complaint. Trinity's body was found a few days later along an equestrian trail at Hacienda Heights.
The case is still under investigation and the authorities are asking anyone with information to come forward.
Hunt is also facing a murder charge. In 2005, he was convicted of sexually abusing children in San Diego County, according to the complaint. The previous sentence could mean a heavier sentence if he is convicted of Trinity's murder, according to court records.
Graham, extradited from Texas while the investigators were preparing the criminal case against her, also has a criminal record. She was convicted in 2016 of instigating a minor to prostitute herself in San Bernardino County, according to the lawsuit.
In case of conviction, Graham and Hunt incur a maximum sentence of life in prison.
On March 8, they were arrested at a border patrol checkpoint in Hudspeth County, Texas. Graham was arrested on warrant, and Hunt was released and continued to return to California, according to the Los Angeles County Sheriff's Department.
Hunt was arrested on March 9 after the police found him sleeping in his car in a parking lot near the San Diego International Airport, the sheriff's office announced.
Hunt was charged with murder and his bail was set at $ 2 million. His indictment continued until 16 April. A public defender will be responsible for representing him.
Investigators have learned that 10 months ago, Hunt and Graham left Trinity to settle with a family member in Long Beach, 15 miles from where his body was found.
Since then, the extended family has seen or heard about these three people only a few times and investigators found that they lived in their car or at a motel in Santa Fe Springs, about 15 km from Hacienda Heights, the sheriff's department said.
According to the Sheriff's Department, there were no open or active cases in the Trinity Child and Family Services Department when she was killed.
