NEW ORLEANS (AP) — Two people have been indicted in New Orleans on second-degree murder charges in a Louisiana man's heroin overdose death.

The New Orleans District Attorney's Office says 45-year-old Michael Willis and 41-year-old Julie Raffray are accused of selling heroin to a Luling man who died Jan. 22 of an overdose. Conviction would mean a mandatory life sentence.

Willis and Raffray are among four people facing multiple criminal counts as a result of Thursday's indictment. The district attorney's news release names Willis as the leader of a narcotics network and says he is currently in federal custody on other drug and weapon charges. State bond for Willis and Raffray was set at more than $1.1 million each. They have not yet entered pleas to the charges.
