Police: 3-year-old boy shot and killed by father, who then turned the gun on himself

A Michigan man shot and killed his 3-year-old son before turning the gun on himself, police say.

On Sept. 1, police officers said they found Dylan Thebo, 3, dead inside his Lowell, Michigan, home from a gunshot wound.

According to authorities, the suspect, Dylan’s father Derek Thebo, shot the child before turning the gun on himself, as both Derek and Dylan were found dead in the home.

In court records obtained by FOX 17, Dylan’s mother feared something like that would happen.

The couple was in the process of getting a divorce and in a personal protective order filed with the court, his wife described Derek as "Dr. Jeckle and Mr. Hyde," FOX 17 reported.

In the court records, Dylan’s mother claimed every time they would fight, Derek would make death threats.

Derek had threatened to kill her, the kids, her family and commit suicide after, even saying he’d save her children “for last,” FOX 17 reported.

In the court documents, Dylan’s mother wrote, "He rattled off the names of my family members and said he knew where they worked, he knew when they were home, and that he could get to them and hurt them," according to FOX 17.

On Mother’s Day, Dylan’s mother said she got a gift from Derek with a message reading, “You will be my last,” according to FOX 17.

FOX 17 said Derek always denied making threats or said he didn’t mean it and that there was nothing he loved more than his son.

Dylan’s mom started a GoFundMe page to help cover the costs of Dylan’s funeral. As of Sept. 7, it raised over $27,000 with an initial goal of $20,000.

"Dylan loved Paw Patrol, excavators, cars and trucks, and singing and dancing. Most of all Dylan loved his momma and big sister Alaina, who was also his best friend," the page read. "His face would light up when playing with Alaina and they always did everything together. They enjoyed going for bike rides, walks, singing in the car, playing with Ava and Riley (family dogs), and giving cards to the local police officers. Dylan loved cheering on Alaina at her soccer games and couldn't wait until he was old enough to play soccer himself."
