Leadville woman charged with first-degree murder after hitting boyfriend with car

A Leadville woman accused of running over her boyfriend on July 8 was charged with first-degree murder on Thursday. Fifty-four-year-old Marie Day faces charges of first-degree murder, a class one felony, vehicular homicide, a class-four felony, and leaving the scene of an accident causing death, a class-three felony.

Leadville police responded to reports of a vehicle striking a pedestrian on 55 Chestnut St. the afternoon of July 8. The victim, who died of injuries later that evening, was identified as 55-year-old John Alexander Martinez, Day’s boyfriend at the time.

Day was arrested in her car, with a $15,000 bond at the time. But as the investigation progressed, and charges of first-degree murder were added, Day’s bond was revoked. She is currently being held in the Summit County jail without bond.



“I don’t believe the victim was deceased yet in original documentation,” Fifth Judicial District attorney Bruce Brown said. “We anticipate we will be able to prove those charges.”

He added that this was the only first-degree murder case that Lake County has seen since 1999.



“That offender is now serving a life sentence, the same prison sentence that the defendant will face here,” Brown said in a statement. “These are serious allegations of domestic violence and abhorrent use of a car as a deadly weapon. Our thoughts go out to the victim’s family.”
