Willis's mother, Treina Harris, is consumed with worry.
"I want to cry, shout, scream but I'm just hoping for the best," said Harris.
The South Side boy was last seen Friday morning when he left to go to summer school at Paul Cuffe Academy.
His mother says he attended class, then was supposed to spend the night at a friend's house before returning home Saturday morning. He never did.
"He always contacts his mother. That's why we're worried," said Wendell Harris, the missing boy's uncle.
Treina Harris says she's called the cell phone of the 14-year old boy her son was visiting several times but has gotten no response.
Although relatives say Julius has never been missing before, his older sister speculates recent problems at school may have sparked her brother's unusual behavior.
"I didn't think he was concerned...just needed help with school," said Williams.
This afternoon, officers canvassed the neighborhood near 88th and Morgan, where Julius was thought to last be.
According an alert, Julius is 4 feet 9 inches tall and weighs 85 pounds. He was wearing a red long-sleeved T-shirt with the word "volleyball" written on it, red shorts, and black suede Adidas shoes.
As the search for Julius continues, all Treina Harris does is pray and wait.
"I believe in God and I hope he comes home safe," said Harris.
