One man has been arrested and another is being sought in the stabbing death of Cory Nicholas Sonnier, whose body was found June 24 in Lake Martin.

Patrick Paul George, 39, of Lafayette, was arrested late Thursday night in Valdosta, Ga., by the U.S. Marshals Service on a warrant for obstruction of justice to first-degree murder, the St. Martin Parish Sheriff’s Office said in a news release Friday.

Authorities are still searching for 19-year-old David James Anderson Jr., who had been with George and is believed to be in Georgia, the release said.

Anderson is considered a person of interest in the case, authorities have said.

Investigators traced George to Georgia because he had fled there once before after being arrested in a Lafayette incident several years ago, said Maj. Ginny Higgins, Sheriff’s Office spokeswoman.

Higgins is referring to George’s September 2007 arrest at The Plaza, where he allegedly stabbed three people during a fight at the now-closed nightclub on Johnston Street.

Court records show that George allegedly cut the men several times with a knife.

George was not charged in the case until April 2009. He is set to go to trial in August on three counts of aggravated battery, according to court records.

George’s criminal history dates back to at least 1990 and involves more than 20 arrests, according to court records.

He is currently being prosecuted by Alan Haney, who handles habitual offenders for the 15th Judicial District Attorney’s Office.

The St. Martin Parish Sheriff’s Office has declined to release any additional information about what role George and Anderson played, if any, in Sonnier’s death.

“Because it is still considered an active investigation, (detectives) are not releasing any further info at this time,” Higgins wrote in an email Friday.

The Marshals Service confirmed during George’s arrest that Anderson had been with George. He is still being sought by authorities in Georgia, the release said.

Anyone with information as to his whereabouts is asked to call (337) 394-3071.
