Montreal police believe missing boy fell in the Rivire des Prairies

Montreal police say they believe a10-year-old boy who disappeared last week accidentally fell and drowned in the Rivire des Prairies.

Ariel JeffreyKouakouwas last seen March 12 in desBateliers Park, which borders the river, after he left his home inAhuntsic-Cartierville to meet a friend.

"For right now, I can tell you that we're not capable of saying without a doubt that it's an accident, but that is the number 1 hypothesis," said Insp.IanLafrenire.

"That's why the investigation is ongoing."

Lafreniresaid Ariel was last seen by a woman who also spoke to him in the park around 11:25 a.m. that morning.

"She left the park. We have cameras that show that young Ariel entered the park, but we do not have any that showed he left it," he said.

In the dayssince Ariel was last seen in des Bateliers Park, police officers and volunteers have combed the neighbourhood and surrounding areas by foot, horseback, helicopter and boat.

Divers also spent Monday and Tuesday submerged in the water of the Rivire desPrairies, but after no signs of Ariel were found, that search was called off by police.

The boy's father,KouadioFrdricKouakou, has repeatedlysaid he believes his son is alive and wasabducted. Their family won't give up on trying to find Ariel, he said.

"My family and I, until proven otherwise, maintain the theory [that it was] an abduction. I'm firm on that. I'm really, really firm on that," he told reporters on Thursday.

He said that while he respects the police and their investigation, he wants all possible leads to be explored.

Kouakou also called on Montrealers and Quebecers to remain vigilant in the search for his son.

"We haven't yet fulfilled our goal, which is to find Ariel. I want us to keep the flame alive to continue our search."

The situation has been hard on his family, especially his wife and young daughter, Kouakouadded.

"Yesterday, [my daughter]asked me, 'Where is Ariel? Is Ariel there?'Those are the questions coming from a little girl. How can I reassure her? How? I don't have the words for that."

Lafreniresaid the investigation is ongoing and police "haven't closed the door" on any scenarios, but they do believe what unfolded that day was a tragic accident.

"As a father, as a police officer, I hope for the best. Believe me," he said. "And we want to answerthat question where is he and what happened?"

'Unprecedented' help

As their investigationcontinues, police have received nearly 700 tips from the public so far.Lafrenire said more than500 volunteers also showed up to help canvass the neighbourhood.

"It's unprecedented," said Lafrenire. "Over the past 25 years, I have rarely seen the public react this way."

There is also a $100,000reward in place toelicit new information thatleads to Ariel.

Montrealers started to pledge money after thefamily initially offered $10,000 to anyone with information about their son's whereabouts.

Here are details about Ariel, who speaks French:

• About four-foot-seven, weighs88 pounds.
• Dark hair and dark eyes.
• Was last seen wearing a black coat with a hood, grey pants and yellow shoes.

Anyone with information about Ariel's disappearance is asked to contact 911.

They are also invited to visit the command post set up outside Galries Normandie on de Salaberry Street, which is about 500 metres from the park.

Police are also asking residents who live near the river in Ahuntsic-Cartierville to be vigilant and contact police if they see any signs of Ariel.

Lafrenire said police officers and emergency responders will continue to search near the riverbank.
