The second killer was Abdel Malik Petitjean, who was listed on France's 'Fiche S' of people posing a potential threat to national security
The second 'jihadist' involved in a French church attack had tried to travel to Syria, prosecutors said today as calls mounted for the prime minister and interior minister to resign after the latest terror attack.
The prosecutor's office said that the second killer was 19-year-old Abdel Malik Petitjean, who was listed on France's "Fiche S" of people posing a potential threat to national security in June after trying to reach Syria from Turkey.
Petitjean, whose face was disfigured after being gunned down by police, had been harder to identify than his accomplice Adel Kermiche, 19, and investigators confirmed his identity after a DNA match with his mother.
'Petitjean described perfectly normal'
Petitjean was described as perfectly normal by his incredulous family and friends.
Unlike his accomplice, Petitjean never raised suspicions for radicalisation among his neighbours, and was unknown to police until last month when he tried to go to Syria.
Petitjean was born to a family of Algerian origin and lived in the quiet lakeside town of Aix-les-Bains in the shadow of the Alps, popular with visitors seeking thermal cures.

The resort is 700 kilometres (430 miles) from the industrial Normandy town of Saint-Etienne-du-Rouvray where Petitjean and Kermich stormed a church and took hostages on Tuesday.
He and Kermiche, also a Frenchman born to an Algerian family, slit the 86-year-old priest's throat at the altar. Another elderly worshipper was severely injured but several other hostages escaped unharmed.
Both assailants were shot dead by police.
'What was inside his head?'
Djamel Tazghat, who manages the local mosque in the Aix-les-Bains suburb where Petitjean lived in social housing, said he recognised the young man in a video published by the Islamic State group in which the two pledged allegiance to the jihadist movement.
"I liked him a lot. We never had a problem with him at the mosque. No strange observations, he was always smiling... It's incredible," he said.
"All the believers are shocked because he was known for his kindness, his calm. We never had any sign of radicalisation. What was going on inside his head?"
Petitjean -- whose identity card was found at Kermiche's house -- had never been convicted of a crime in France so his DNA and fingerprints were not available to speed up the identification process.
Sources say that after being gunned down by police, the second attacker's face was too disfigured to allow him to be clearly identified, and that his DNA had to be matched to that of his mother.
He came onto the radar of French police in June after he tried to travel to Syria from Turkey, and was placed on France's "Fiche S" of people posing a potential threat to national security.
Sources close to the investigation said Petitjean "strongly resembles" a man hunted by anti-terrorism police in the days before the attack over fears he was about to carry out an act of terror.
The sources said France's anti-terrorism police unit UCLAT sent out a note four days before the attack -- saying it had received "reliable" information about a person "about to carry out an attack on national territory".
Three members of Petitjean's family were taken in for questioning, said a source close to the investigation.
Unlike Kermiche and other jihadists carrying out recent attacks in Europe, there have been no indications that Petitjean suffered from psychological problems.
'Hard to believe'
After finishing high school in 2015, Petitjean worked part-time sales jobs and his resume said he liked science-fiction movies, video games, music and boxing.
"It is hard to believe. He was against Daesh. He was not radical at all," said Hakim, 17, who claimed he was Petitjean's friend.
His mother, Yamina Boukessoula, refused to believe her son was involved when she spoke to AFP just hours before the official confirmation.
"He was a good French citizen. He is gentle. I know my child, I know my son. He was not involved at all," she said.
Petitjean grew up with two sisters in a blended family.
His mother said he had left their home on Monday to visit his cousin in the northeastern city of Nancy.
His last text message to his mother came on Tuesday morning, just before the attack: "Don't worry, everything is fine... I love you."
On Wednesday afternoon his mother, still refusing to believe her son was involved, sent him a final message: "Malik, it's mum, I don't know where you are. I have bad news. Call me. The police have come, they are talking rubbish. I hope nothing has happened to you my son. I love you. I miss you so much."
'Government guilty of being unable to stop attacks'
The attack came as the government was already facing a firestorm of criticism over alleged security failings after the Bastille Day truck massacre that left 84 dead two weeks ago.
A brief show of political unity at a mass attended by different faiths in Paris on Wednesday quickly dissolved as Prime Minister Manuel Valls and Interior Minister Bernard Cazeneuve faced fresh calls to resign.
"If the government is not responsible for the wave of terrorism, it is guilty of not having done everything to stop it," said Laurent Wauqiez, the deputy leader of the right-wing Republicans party in an interview with Le Figaro newspaper.
"Manuel Valls and Bernard Cazeneuve must go because they refuse to take vital measures to fight Islamism. We need a new government, determined to act".
France to form National Guard
The French government has assured the country that everything possible is being done to protect citizens, while warning that more terror attacks are inevitable, after three major strikes and several smaller attacks in the past 18 months.
President Francois Hollande confirmed today that the creation of a National Guard to be made up of reserve forces, after the government earlier urged "patriots" to sign up to become reservists.
Hollande said parliamentary consultations on the formation of the force would take place in September "so that this force can be created as fast as possible to protect the French".
The government has faced tough questions as it emerged both church attackers were on the radar of intelligence services, and had tried to go to Syria.
One of the criticisms is that Kermiche had been released from prison while awaiting trial on terror charges after his second attempt to travel to Syria.
