Two men with ties to one of the three gunmen who terrorized Paris were handed preliminary charges Friday, the Paris prosecutor said, describing hundreds of texts, regular meetings and DNA recovered from a stun gun among the belongings at a bloodied kosher supermarket, reports the Associated Press.

The two men, identified as Amar R. and Said M., were given preliminary charges for participation in a terrorist group with the intent to commit crime.

Prosecutors said Amar R., a jailhouse acquaintance of Paris terrorist Amedy Coulibaly, had exchanged more than 600 texts with Coulibaly from September to January and met him on Jan. 5 and Jan 6. That was just a day before two brothers killed 12 people at the Charlie Hebdo satirical newspaper in Paris on Jan. 7 and before Coulibaly shot dead a policewoman on Jan. 8 and killed four of his hostages on Jan. 9 at a Paris kosher grocery store.

DNA from Said M. was recovered from a stun gun in Coulibaly's belongings at the market, the prosecutor said.
