Family members of a man accused of trying to kill himself and his daughter said they are more shocked than anyone.

Police said Derrick Summers ran across Interstate 77 on Sunday, holding his daughter, and was hit by oncoming traffic.

Both he and the two-year-old, Lizziah, are in the hospital.

Summers' family said Wednesday that the man who ran into traffic is not the person they knew.

"The person that he was on the night of that incident," his sister Naisha said, "I don’t know that person at all."

Naisha Summers made no apologies for her brother, and called him a "monster" for what he did Sunday.

But she said that's not the brother she knew, the brother seen in pictures holding his daughter and smiling.

His family said only since the accident have they learned about court records that allege he had made threats to the child's mother last month.

He was granted supervised visitations with his daughter on weekends.

His stepsister said he was taking the girl back to her mother on Sunday before the incident on the interstate.

"I mean, he left the house and in 20 minutes we get a phone call and the whole world just changed," stepsister Denise Royal said.

Naisha Summers said they are not being allowed to get updates on the condition of her brother or his daughter.

Derrick Summer will face child abuse and attempted murder charges.
