A father of two young children found dead inside a hot truck was released on bond after the Tulsa District Attorney's Office said surveillance video shows the children got into the car on their own.

The district attorney said in a statement that video from a neighbor's home confirmed the two young children got into the truck on their own and never got back out.

The DA's office issued the following statement on Monday:

Police booked Dustin Lee Dennis Tulsa County Jail, and he was being held on a $1 million bond, according to records.

Tulsa Police and the Child Crisis Unit received a call around 5:30 p.m. on June 13 at a neighborhood near 61st Street and Utica Avenue.

When officers arrived, they found a three-year-old and a four-year-old boy and girl deceased.

The father told police he went to QuikTrip with his children and came back home to take a nap.

He said he fell asleep between four and five hours, and when he woke up, he found his kids dead inside the truck.

He then carried them to the living room.

No previous underlying health conditions are suspected for the two children; however, the medical examiner is looking into the cause of death.

TULSA, Okla. — Five more burials were found during an excavation Thursday in a mass grave at a Tulsa cemetery that officials say was created during the 1921 Tulsa race massacre.

The findings on Thursday were just the latest burials discovered amid the excavation at Oaklawn Cemetery in Tulsa, dating back to last year. They also come as the country commemorated the 100th anniversary of the deadly riots earlier this week.

According to Kary Stackelbeck, State Archaeologist of the State of Oklahoma, the additional burials bring the total number of people known to be buried in the mass grave to be 20. Twelve burials were discovered during the test excavation last year in October.

After searches for mass graves continued on June 1, the excavation team expanded their research area to try and find graves in the southeastern corner of the cemetery after evidence showed they were near a grave shaft. It was there they found additional burials.

The search for burials is a part of the 1921 Graves Investigation that the city of Tulsa is conducting to try and locate victims of the Tulsa race massacre.

After the excavation stage, the research team will document their findings and then send the remains to be tested for DNA to see if they can be linked to the Tulsa Race Massacre. More information about finding mass graves can be found on the City of Tulsa's website.
