A Birmingham boy critically injured when he was hit by a car while trick-or-treating was all smiles Thursday as he was released from the hospital four months after the tragic Halloween crash.

With a lollipop in his mouth and an impressive command of his wheelchair, 4-year-old Steven “King” Allen zoomed back and forth in the lobby of Children’s of Alabama, eager to finally make his getaway.

“He’s ready to go home,’’ said his mother, Anita Brunner Allen. “He’s rushing to get us out the door.”

“These four months have been an up and down rollercoaster for us,’’ Brunner-Allen said. “There were a lot of nights we were uncertain about things.”

“But the care at Children’s is amazing,’’ she said. “It’s bittersweet leaving. I’m ready to go home, but I’m going to miss them.”

Two people have been charged in the hit-and-run that injured King.

Justin Clay Carter, 37, is charged with three felony warrants for leaving the scene of an accident. A grand jury affirmed those charges earlier this month.

Anna Rogers, 35, is charged hindering prosecution.

The wreck happened just before 8 p.m. Tuesday, Oct. 31, near the intersection of 9th Avenue South and 56th Street South at about 7:54 p.m.

King had been to a Halloween event at his family’s nearby church and was on last stop of his trick-or-treating route that Tuesday night when tragedy struck.

Dressed as the Black Panther, King was on 56th Street South in Birmingham’s Crestwood neighborhood, when authorities and family said he and two others – including an infant – were struck at a high rate of speed by a vehicle whose driver did not stop.

King was with his oldest sister and her best friend, both in their 20s, and the friend’s children, including her 9-month-old son. King had just turned 4 the previous week.

“That car just came up the road speeding, hit him, didn’t even break stride and kept going,’’ his father, City of Birmingham employee Steven Allen Sr. previously told AL.com.

“That’s the area we’ve been going to for years because they always have big decorations,’’ Allen said. “That was their last stop before they came home.”

“Everything just happened so fast,’’ said King’s sister, 23-year-old Kadeidra Gouch, who was with him. “I’m just overwhelmed at the moment.”

The neighborhood is popular with trick-or-treaters, partly because of the elaborate yard decorations.

“They told me it took the paramedics almost 10 minutes to get up the street, that’s how many kids there were,’’ Allen said.

The Allens received a telephone call as soon as King and the others were struck. Allen said he rushed to the scene, but King had already been transported by Birmingham Fire and Rescue Service to the emergency room.

The 25-year-old woman and her infant son sustained non-life-threatening injuries.

Gouch, King’s sister, was not injured.

King suffered damage to his liver, kidney, and a lung.

He also sustained a spinal cord injury which led to autonomic dysreflexia, a dangerous syndrome involving an overreaction of the autonomic nervous system that causes a sudden and severe rise in blood pressure.

“He sleeps on a ventilator and has a trach,’’ in Brunner-Allen said. “He doesn’t have any use of his legs right now but that doesn’t mean he won’t.”

“So, I’m hopeful,’’ she said. “He’s come a long way.”

King’s parents have stayed by their son’s side in the hospital since Halloween.

“We’ve gone home for like two days of the week,’’ Brunner-Allen said. “Me and Dad have been here the entire time.”

She said King doesn’t talk much about the crash.

“We asked him if he remembered,’’ Brunner-Allen said. “He said it was the street and the cars.”

The family has had to move to a new home to accommodate King’s medical and physical needs. Brunner-Allen recently lost her job because she’s been with her son in the hospital.

The family also is looking for a home nurse with pediatric experience.

A GoFundMe for the family has raised more than $20,000 since October and remains active for the many ongoing needs. Donations can be made here.

Despite the challenges, Brunner-Allen said she’s hopeful for the future.

“He’s come a long way. He’s always in good spirits,’’ she said. “I don’t think it affects him so much because he’s so young. He’s just a happy kid.”
