Hot Car Killer's Ex Makes Emotional Testimony: 'He Destroyed My Life!'

Leanna Taylor took the stand again this morning for an emotional cross examination for ex-husband Justin Ross Harris' trial in the hot car death of their 22-month-old son, Cooper.

As RadarOnline.com readers know, Harris is facing malice murder, felony murder and cruelty to children charges after Cooper was found dead in the back seat of his SUV in June 2014.

Harris claimed that he forgot to drop his son off at daycare after picking up a fast food breakfast and didn't realize he left the 22-month-old in the car on a 90-degree day. Later, Harris left the office for lunch with co-workers, bought light bulbs and even put them in the car without noticing that Cooper was (presumably) dead in his rear-facing car seat.

Wednesday morning, Harris' ex-wife was grilled by prosecutors about her husband's double life, including multiple online affairs, as she defended him against murder charges.

"You would agree that that was somebody completely different than the person you married?" the prosecuting lawyer asked Taylor.

"I would agree that was a part of his personality, that he did not share with me," she replied of her husband's infidelity.

"Did he ever tell you that he'd gotten up at 5:43 a.m. or was awake at that point messaging strangers?" the prosecutor asked.

"No, he destroyed my life," Taylor replied tearfully. "I'm humiliated. I may never trust anybody again, the way that I did. If I never see him again after this day that's fine."

Despite Harris' affairs, Taylor insisted he was a good father and no murderer.

Since their divorce in February, Taylor said she has not spoken to her ex and moved to Alabama to be closer to her family.
