A 32-year-old man who allegedly drowned his two sons on the first day of school and led police on a manhunt has been apprehended.

Naim Mohammed was caught after a foot pursuit near a neighborhood creek. Helicopters, the SWAT team and dogs were on the ground pursuing the suspect.

Mohammed is accused of drowning the boys ? ages 3 and 5 - whose bodies were found in his car at East Ledbetter and Singing Hills Drive.

Officials say around 12:40 p.m., a 911 caller said her son had drowned her grandchildren. The caller also told the fire department she had the children with her and was waiting for paramedics. The children were pronounced dead at hospital.

Deputy Chief Craig Miller of the Dallas Police Department on Monday said investigators believe Elijah Mohammed, 3, and Naim Mohammed, 5, were drowned. Investigators are trying to find out where the children were killed.

We [were] hoping for them to start school today and be with the rest of the kids and enjoy life, but someone ended their life shortly, said Gabrielle Armstead, the children's aunt, to MSN.

ABC reported that the mother of Mohammed's children, who doesn't live with him, reported that he forcefully assaulted her and then kidnapped her, along with the two boys, as she was taking them to school at Julia C. Frazier Elementary around 7:15 a.m.

The woman said she managed to jump out of Mohammed's Toyota Matrix and call police.

Instead of issuing an Amber Alert, a Critical Missing Persons Report was filed, and police said the Amber Alert was set for one p.m.  

We were trying to follow the trail we had, Miller told ABC, adding that police knew early on who they were pursuing.

Miller said the suspect is cooperating with their investigation.

I think everyone is hurt in this case, he said. I think officers who open the back hatch of the vehicle... it makes each of us think about our own children... We are very sorrowful for what took place, and the children and their families who were involved.
