Adel Kermiche has been named as one of the Islamic State-inspired terrorists who murdered a priest in a church in Normandy.
Here's everything we know about the 19-year-old.
Kermiche was twice arrested last year for trying to get to Syria
The teenager was released from prison in March 2016 but placed under close surveillance
Kermiche was wearing an electronic tag and was on probation when he killed the priest
He grew up in an estate in Saint-Etienne-du-Rouvray - the town where the priest was killed
A family friend said Kermiche's sister is a doctor while his mother is a professor
His family alerted authorities to his radicalism to try to stop him from going to Syria
A video has also emerged showing Kermiche pledging allegiance to the so-called Islamic State
