ST. LOUIS (AP) — A man has been ordered to spend two decades in prison after admitting in court that he fatally shot his girlfriend and a groundskeeper in 2014 near St. Louis.

Adrian Houston, 39, of University City pleaded guilty Friday to two reduced second-degree murder counts. He also pleaded guilty to counts of armed criminal action, burglary and domestic assault.

Authorities say Houston killed Jessica Thompson, 25, and Tony Jordan,  32, who lived and worked in the apartment complex where Thompson was slain.

The crime drew extra public attention because of allegations that the victims might have been saved had a St. Louis police dispatcher not sent officers to the wrong address. That error is the subject of an unresolved lawsuit by the victims’ relatives.
