After picking up the truck on July 11, Bouhlel staked out the site of the carnage on the Promenade des Anglais at 6 pm on July 12 when video surveillance showed him briefly stopping the truck along the road, and again at 10 pm on July 13, roughly 24 hours before he would launch his attack.
"I also wanted to show my support for France at the moment of silence today because the USA and France are in this together in this bad fight against terrorism", Hartley told The Associated Press as she arrived at the Nice city hall to meet mayor Philippe Pradal.
Bouhlel and a 30-year-old French-Tunisian with no previous convictions had phoned each other 1,278 times in a year, Molins said.
As investigators continue to look into the attacker's motives, his uncle in Tunisia, Sadok Bouhlel, told The Associated Press his nephew had been indoctrinated about two weeks ago by an Algerian member of the Islamic State group in Nice.

French Prime minister Manuel Valls (R), French President Francois Hollande (C) and French Foreign minister Jean-Marc Ayrault visit the Interministerial Victim Support Unit (CIAV) at the Foreign Ministry in Paris on July 16, 2016. Six people were in custody on Monday including a 38-year-old Albanian suspected of providing Bouhlel with a pistol he used to fire at police during the attack.
Earlier Thursday, French officials defended the government's security measures in Nice on the night of the Bastille Day attack, even as the interior minister acknowledged that national police were not, as he had claimed before, stationed at the entrance to closed-off boulevard during the attack.
However Paris prosecutor Francois Molins said there was no direct evidence of the Tunisian's links to IS - which has claimed him as one of their "fighters". Garino said the woman, the mother of Bouhlel's three children, had not been in contact with the attacker since they were in the middle of divorce proceedings.
"Each time he had a crisis, we took him to the doctor who gave him medication", Mohamed Mondher Lahouaiej Bouhlel told France's BFM television.
Cazeneuve then launched an internal police investigation Thursday into the handling of the Nice attack.

The study showed that about four in every five Islamic State recruits have criminal records, while some 20 percent were diagnosed with mental health issues. "They are absolutely exhausted after a year and a half of intense efforts to try and protect this country", he said.
"The painful reality here is that if it wasn't going to be this promenade, it would have been any other promenade".
France had put intense security in place for Euro 2016, the worldwide soccer tournament that just ended.
Republicans leader and former president Nicolas Sarkozy, who is eyeing another run for the top job in 2017 elections, has called for anyone showing signs of being radicalised to be forced to wear an electronic tag, placed under house arrest or kept in a detention centre.
