Authorities on Monday were still searching for a Lafayette man accused of killing his girlfriend at a home in Duson over the weekend.

Miles Joseph Guidry, who turned 28 on Saturday, is wanted on second-degree murder in the death of Claire Christine Walley, 26, according to the Lafayette Parish Sheriff’s Office.

Walley’s body was found Sunday morning inside a home in the 400 block of Lagneaux Road, along with her unharmed infant.

Capt. Mike Andrus, criminal investigations commander with the Sheriff’s Office, said detectives are following leads but have not found a trace of Guidry since the killing, despite reports his car had been found abandoned in Lake Charles.

“We don’t have any information. We haven’t located his car. We do have a few leads here and there,” Andrus said.

Investigators have not released information on Walley’s cause of death. An autopsy is scheduled Tuesday, said Keith Talamo, chief investigator for the Lafayette Parish Coroner’s Office.

Guidry, 603 Wilson St. Apt. 1, is due in court on Thursday for a hearing on unrelated charges of simple criminal damage to property, illegal discharge of a firearm and aggravated flight from an officer.

In those counts, Guidry is accused of crashing his car into the now-demolished Lafayette Habitat for Humanity building on Johnston Street in April 2014. After the crash, he allegedly shot a .357 revolver into the air and fled from a Lafayette police officer, according to court records.
