(CNN) A woman was arrested Monday on suspicion of murder after the body of her 9-year-old daughter was found in a duffel bag earlier this month, authorities said.

Taquesta Graham, 28, is expected to be charged with murder on Wednesday, according to the Los Angeles County Sheriff's Department. She is the second suspect, the agency said, after her daughter, Trinity Love Jones was found dead inside a black duffel bag on March 5.

Graham's arraignment will follow the filing on Wednesday, the sheriff's department said.

Last week, Graham had been extradited from Texas to Los Angeles, as investigators prepared a criminal case against her. She was initially being held in the custody of the LA County Sheriff's Department on an unrelated warrant.

It's not clear if Graham has legal representation at this time.
