Jurors from St. Charles County deliberated for just over an hour, then convicted David Hosier of first-degree murder for killing Angela Gilpin in September 2009.
They also found him guilty of armed criminal action, burglary and being a felon in possession of a weapon.
The jury returns at 9 a.m. Thursday to decide if Hosier should get the death penalty for the murder conviction.
More details in Thursday's News Tribune.

Angela Gilpin was shot six times, including two shots to her head, and Rodney Gilpin died from three shots in the chest, Boone County Medical Examiner Carl Stacy testified this morning.
Stacy performed the autopsies on both victims a day after they were murdered on Sept. 28, 2013.
He was the last witness before Cole County Prosecutor Mark Richardson ended the state's presentation of evidence.
Public Defender Donald Catlett called two witnesses this morning, including Malena Jimenez, a Highway Patrol criminalist who said both Gilpins were eliminated as potential DNA matches for three samples from the jeans suspect David Hosier was wearing when he was arrested in east-central Oklahoma, about 5 1/2 hours after the murders.
She said no other samples had been offered for testing.
And, she told Richardson under cross-examination, DNA testing can't link a sample to a specific time it would have been left at a scene.
Catlett also called Jefferson City Police Detective Mark Edwards, who testified he test-fired Hosier's Sten submachine gun in 2010, several months after the Patrol had test fired it - and that he originally thought the murder weapon was a 9 mm handgun.
Edwards told Richardson that no DNA testing was requested from inside Angie Gilpin's apartment, because several people told officials Hosier had been there several times before the murders.
Hosier, 58, is charged with first-degree murder for both deaths, with evidence this week suggesting he was upset that Angie, 45 - who had established a relationship with Hosier while separated from Rodney, 61 - was leaving Hosier to reconcile with her husband of 21 years.
But an attorney clarified for the News Tribune that this week's trial only is for Angie Gilpin's murder, and that a trial involving Rodney Gilpin's death still is to be determined.
A jury from St. Charles County is hearing the evidence.
If they convict Hosier of Angie Gilpin's murder, Richardson intends to seek the death penalty.
