SPOKANE, Wash. -

The murder trial for Jason Flett, who is accused of killing Ramona Childress in 2012, is underway at the Spokane County Courthouse.

Childress' body found on a property in Elk last October.

Prosecutors say Flett killed Childress because she had information that could send him back to jail.

On Tuesday Flett's ex-girlfriend took the stand testifying about the physical abuse she and Childress suffered and about the night Childress was killed.
