COLUMBIA, S.C. (NewsNation) — Broadway dancer Zelig Williams, who has worked on shows such as “Hamilton” and “MJ the Musical,” was last seen Oct. 3 carrying professional headshots as he left his house in Columbia, South Carolina, according to Williams’ mom Kathy. 

Kathy Williams, along with cousin Mieoki Corbett-Jacobs, joined NewsNation’s Ashleigh Banfield on Monday night to discuss the latest details in the mystery surrounding Zelig’s disappearance.

Kathy said she found it strange her son was awake at 2:30 a.m. the night before he went missing; he asked her if she was OK before going to bed.

“I told him, yes, I’m OK. And he went back to bed,” Williams said on “Banfield.” “The next morning, I sat on my front porch reading my devotions, and Zelig came out. I said ‘Let me see that photo you have in your hand.’ He just looked at me and said something, but I didn’t understand what he was saying. He got in the vehicle, and he left. I didn’t see him anymore.”

Shortly after Williams left home, friends said they got an automatic emergency notification from his iPhone minutes later. Williams’ empty car was found undamaged in an isolated parking lot for the Palmetto Trail a day after deputies determined he was driving at the nearby Congaree National Park about 15 miles (24 kilometers) from downtown Columbia, according to the Richland County Sheriff’s Department.

Williams’ family said at a news conference that they think he stopped taking his medication just before he disappeared and are worried he might be behaving erratically or even could appear in a trance-like state to people looking to help him.

Tips from the community are likely going to be critical to finding Williams, Sheriff Leon Lott said at a news conference at the department’s headquarters, joined by family members of the dancer.

Deputies said nothing, including foul play, has been ruled out in the case: “We have used every means of manpower and technology that is available,” Lott said.

They also are asking churches to pay special attention to anyone new, because Williams was visiting in an effort to find a place to worship. Williams, 28, had moved back to his hometown of Columbia a few months earlier.

Williams is the light for his family, cousin Mieoki Corbett-Jacobs said. His two sisters died in a car crash 20 years ago and inspired him to start dancing, she said.

Williams’s disappearance has also drawn the concern of the broader theater community, including Hugh Jackman.

Williams’ colleagues on Broadway are also asking for help. Jackman, who worked with Williams in “The Greatest Showman” tour, posted Williams’ picture on his Instagram feed this month.

“Zelig we love you and are praying for your safe return,” Jackman wrote.
