Helric Fredou, a French police commissioner, killed himself last week in Limoges, France.
Commissioner Fredou had met with the relatives of a victim murdered in the terrorist attack at the Charlie Hebdo offices in Paris before taking his life.
Conflicting reports say he committed suicide on Wednesday or Thursday.
Cherif and Said Kouachi, who were brothers, shot and killed 12 people last Wednesday morning in Paris.
The brothers were found and killed by French police about 20 miles northeast of Paris on Friday, which Commissioner Fredou did not live to see.
"We are all shocked. Nobody was ready for such developments," a local police union rep told reporters, according to Sputnik.com.
