SAGINAW, Mich. -- A 15-year-old high school student has been charged with attempted murder on accusations that he opened fire at a middle school football game, injuring four people.

Two students and two adults were wounded in Wednesday’s shooting.

Saginaw County Prosecutor Michael Thomas says the suspect is being charged as a juvenile.

Thomas says the case could be upgraded to an adult prosecution soon should he decide that is warranted.

Police said Anthony Green was standing near the media center next to the football field when he shot the first victim at close range.

Green then turned the gun on another student standing nearby. The shots from the gun may have then ricocheted to the left, hitting a couple walking near the area.

Green is currently being held at the Saginaw County Juvenile Center.

Police also asked the prosecutor's office to consider charging him as an adult.

An Arthur Hill sophomore was shot in the neck and remains hospitalized at Covenant Medical Center in critical condition.

Police said he will likely survive but may never walk again.

The suspected gunman targeted the sophomore, but the other three people were innocent bystanders, police said.

A man and woman, and an Arthur Hill freshman were treated for gunshot wounds to the legs and released, officials said.

Police said they believe the shooting was over a disagreement earlier in the day.

The game was wrapping up its third quarter between Central Middle School and South Middle School when shots rang out.

About 300 people were nearby when the shooting occurred in the vicinity of football field in broad daylight.

People attending the game recognized the shooter and informed police, officials said.

"We heard two small pops and thought they were firecrackers," said witness Dia Patterson. "It's sickening to think that you can't come to a junior high game and be safe."

This contest was to be the last home game on the South Middle School campus, as next year the student body is moving to a new location.

Crisis counselors will be available at South Middle School for any student having difficulty with the shooting.

Anyone with information about this shooting is asked to call police at 989-759-1245.
