A jury found Lawrence Boyle guilty on two counts of first-degree murder in the death of Sierra Jamison.

The video in the player above is from a previous report.

In September 2023, Jamison's mother found her in a garage outside the home she had been renting in the 7800-block of South Indiana Avenue, which she shared with her 6-year-old son.

Her mother said her daughter had just celebrated her 30th birthday and was working as a phlebotomist.

Boyle is due in court on January 5 for pre-sentencing motions.
