As Twitchy reported Tuesday night, a gunman opened fire at a Christmas market in the town of Strasbourg, France, killing three and leaving one victim brain-dead.

The suspect, Chérif Chekatt, known to be on a terror watchlist, managed to escape but was shot and killed by French police Thursday after a two-day manhunt. The Wall Street Journal reported that the extremist group Islamic State described Chekatt as “a soldier” on its Amaq news agency.

Most people had guessed the shooter’s motive on Tuesday night, but get this: Chekatt has been convicted 27 times.

TheBlaze reports that five people have been arrested in connection to the attack, including Chekatt’s parents, two of his brothers, and a member of his “entourage.”

Rukmini Callimachi is a correspondent for the New York Times who covers ISIS:

According to The Guardian, Chekatt was born in Strasbourg in 1989 and dabbled in petty crimes but moved into Muslim extremism in a prison stay between 2013 and 2015. By the age of 29 he had 27 convictions for theft and violence.

“On the morning of the Strasbourg attack,” The Guardian reports, “he was to have been arrested in connection with attempted murder linked to an armed robbery that went wrong last summer.”
