Earlier in the week, a Lane County jury found Robert Cromwell guilty of first degree murder and unlawful use of a weapon.
Cromwell used a baseball bat to beat 26-year-old Eugene resident Casey Wright to death in November 2013.
Investigators say Cromwell was angry about the end of his relationship with Wright, and killed her after reading text messages she had sent to other men.
Prosecutors say the 33-year-old confessed the killing to a police detective as well as a triage nurse in the emergency room at McKenzie-Willamette Medical Center shortly after the murder.
Cromwell’s murder sentence carries a minimum of 25 years in prison.
