SEMMES, Ala. (WKRG) — Derek Johnson is speaking out after finding his children and estranged wife dead in their Semmes home on September 28.

After spending the weekend grieving over the unimaginable, he’s still trying to pick up the pieces of what he can of his family.

“I am just dead inside, and I’ve cried all weekend, and I just feel sick,” Derek Johnson said.

Derek found his wife, Nancy, and children, Jacob, 2, and Mia, 5, dead inside their home on Evergreen Court in Semmes last Thursday. Derek lives in a camper behind the home.

He explained that he knew something was wrong when he noticed the lights were all off at the home for more than 24 hours.

“I opened the door; I noticed Mia and Jacob were lying on the couch with blankets on them, and I walked over to Jacob and put my hand on his back to try to wake him up,” Derek recounted. “And he was he was stiff as a board. He had foam. He had foam coming out of his mouth and walked over to Mia. She had foam coming out of her mouth and I walked into the master and there was a there is a bathtub full of blood.”

Derek believed the tragedy stems from marital issues between him and Nancy, citing the COVID-19 pandemic as the beginning of the problems.

Court records show the couple’s ongoing marital issues as Nancy initially filed for divorce in April, but the two later reconciled in June.

Derek filed for divorce later in September.

After spending the past weekend coping with the loss of his entire family, Derek said he’s unsure of how he’s going to move forward.

“I feel lost now,” Derek said. “I have nothing, absolutely nothing. And I don’t know how I’m going to recover. I… I don’t know. I just know I’m going to miss them all.”

According to Semmes PD, they had responded to several domestic violence calls at the home.

Mobile County Sheriff Paul Burch said Derek has not been ruled as a suspect in any of the deaths as the investigation has been ruled as a murder-suicide.
