Man On Tulsa Tower For 5 Days Refuses Police Requests To Come Down

A man in Tulsa climbed to the top of a 300-foot tower on Thursday and has refused to come down.

Police fear that William Boyd Sturdivant II could be dangerously dehydrated, because he's refused offers of food and water since Friday, The Tulsa World said.

However, on Monday, he requested a Sprite, Dr. Pepper, Rooster Booster energy drink and a cappuccino, CBS said.

During his five days on the tower, he's hardly slept, getting shuteye during the day on Saturday and again Sunday night, CBS said.

Sturdivant, 25, has a history of mental illness, police told TV station KOTV.

In the morning, he's crowed like a rooster at the sun and told police he prefers the tower to being on the ground, CBS said.

The fire department raised a crane up to Sturdivant's perch, but he refused to end his standoff, the station reported.

"They've already been up three times and made it very, very easy for him to get in the bucket. He's refused, so we offered it to him one more time," negotiator Cole Butler told KOTV. "He started getting agitated and irritated with me, then went into his dreaming state, rocking back and forth."

Sturdivant denies that he's suicidal and Butler said he doesn't think Sturdivant plans to kill himself.

The day before Sturdivant ascended the Clear Channel communications tower, he was found on the roof. He was reportedly chased away, but came back on Thursday.
