Martineau Murdered Girlfriend in May 26 Attack, Police Say

The defendant also is charged with a separate domestic assault on the woman.

A second-degree murder and second-degree domestic assault charges were filed Friday against Steven John Martineau, 48, of the 400 block of Tower Grove in St. Charles.

Martineau is 50, who died June 10 from her injuries.

St. Charles Police said Martineau and Cerutti argued at their home 400 block of Tower Grove Place in St. Charles. During the argument, Martineau attacked Cerutti, beating her into unconsciousness, police said.

She never recovered from her injuries and died 15 days later.

According to a news release, investigators used inconsistencies in Martineau’s account of how Cerutti sustained her injuries and information from other sources to develop the case.

Martineau has been held on misdemeanor charges of third-degree domestic assault on Cerutti in a February. He is being held in St. Charles County jail in the St. Charles County Jail in lieu of a cash-only bond of $50,000 since the incident in May.

Martineau was held on an outstate warrant from Michigan involving child support charges.

I am so sad and happy at the same time. This is my mom, Im happy charges have been filed against this douchebag but at the same time my mom is gone! It sickens me the thought of what was goin on and going through her head before the moment he put his hands on her. The whole thing sickens me. I hope he suffers for a long time in prison and endure much more pain then my mom did the last 2 weeks of her life. Bubba will get him sooner or later. Justice will be served for my mom!
