Five people detained in connection with the three days of bloodshed in France have been released from custody, the Paris prosecutor's spokeswoman said Sunday.

The gunmen who carried out the attacks on the satirical newspaper Charlie Hebdo, a policewoman outside Paris, a kosher market and a printing house all died after standoffs with police.

Family members of the attackers have been given preliminary charges, but prosecutor's spokeswoman Agnes Thibault-Lecuivre said five people were freed from custody late Saturday and no one remained in detention over the attacks that left 17 people dead.

The widow of one of the gunmen, who has been named as an accomplice, is believed to have traveled to a Turkish city near the Syrian border and then all traces of her were lost, according to a Turkish intelligence official, who was not authorized to speak on the record.

Brothers Said and Cherif Kouachi methodically massacred 12 people at the Charlie Hebdo offices, led police on a chase for two days and were then cornered Friday at a printing house near Charles de Gaulle Airport. Separately, Amedy Coulibaly shot a policewoman to death and attacked the Paris kosher market, threatening more violence unless police let the Kouachis go. Four hostages died.
