COLUMBIA — Police have arrested a Columbia mother and her boyfriend on suspicion of killing her infant daughter.
Anna E. Steele, 24, called 911 about 2:50 a.m. Friday and told the operator that she and her boyfriend had woken up to find that her 8-month-old daughter, Finley Steele, was not breathing, said Sgt. Joe Bernhard of the Columbia Police Department.
Paramedics and police arrived at 504 Woodridge Drive, where the couple lived, shortly before 3 a.m.
The emergency personnel transported the infant to a local hospital, where she was pronounced dead. An investigation revealed that Finley's death was caused by physical trauma, not natural causes.
Police arrested Cody M. Baker, 31, at 9:30 p.m. Friday and Steele at 3 a.m. Saturday. Both were arrested at the police department on suspicion of second-degree murder. Bernhard said he thought charges would be filed sometime Saturday.
Bernhard said he would not comment on the nature of Finley's injuries. The investigation into her death is continuing, he said.
*Baker and Steele were being held at the Boone County Jail Sunday morning. Baker was being held on a $2 million cash bond and Steele was being held on a $1 million cash bond.
Bernhard said he did not know whether anyone else was living with Baker and Steele at the Woodridge Drive house when the infant died.
Steele had no other children, Bernhard said.
