On Monday, lead investigator, Cobb County Police Detective Phil Stoddard returned to the stand, and prosecutors showed the jury videos that demonstrated -- in real time -- how long it took for Ross Harris to drive between the Chick-fil-A restaurant and his office.

Ross Harris faces a number of charges, including malice murder and felony murder in the June 2014 death of his young son, Cooper. The 22-month-old was found in the backseat of Harris' SUV. Harris insists the incident was a tragic accident.

Videos were also shown Monday that demonstrated how long it would take to go to the daycare where he should have taken his son after breakfast that fateful morning.

Surveillance video from the daycare center which showed Harris bringing his son to the daycare center on the day before his death was also shown.

Stoddard was asked about Harris' own video searches as that information was introduced in court on Monday.

During a portion of the Cobb County Police interrogation, Harris mentioned he had recently seen a video about the effects of leaving an animal inside a hot car. Police recovered that particular video and played a portion of that video in court.

"I watched that (the online video), and that would be terrible if my son was in the car," Stoddard said, reading Harris' words from the transcript of the police interview. "I would hate that."

At one point during the initial police interview, Harris actually began to argue the legal points of the definition of cruelty with investigators. This portion of the interview was captured on a hand-held camera.

Last week the prosecution primarily focused on sexual online and offline relationships Harris had with multiple women, two of which who were minors. The jury was given details of Harris' encounters with these women. They they were shown explicit photographs and heard the transcripts of the conversations the women had with the defendant through text messages and various messaging apps.

The biggest day however proved to be Friday when Stoddard took the stand.

Stoddard showed jurors videos of the initial interview with an investigator. The videos also showed Harris wailing and crying by himself and later with his wife.
