METHUEN — A wounded Methuen teen continued his recovery in a Boston hospital while a Haverhill 17-year-old was charged and held on $500,000 bail in a Sunday afternoon shooting on Davis Road, according to police. 

The Haverhill male is charged with assault and battery causing serious bodily injury, armed assault to rob, carrying a loaded firearm and illegal possession of a firearm without a license, police said.

Investigators found him Wednesday in Haverhill at a location they would not specify. And because he is age 17, he is considered a juvenile under the law and police did not release his name. 

The youth now faces arraignment in juvenile court, which is not open to the press or the public. 

Meanwhile, Alex Vermette, 17, of Methuen, remained in critical-but-stable condition at Brigham and Women's Hospital in Boston, police said. 

Vermette was shot and pushed from a Honda Accord on Davis Road just after noon on Sunday, police said. 

He was initially taken to Lawrence General Hospital, where he underwent surgery, and later airlifted in Brigham and Women's Hospital in Boston. 

Family members on Tuesday sought donations through a crowd-funding website, "Go Fund Me." They said Alex, a Methuen High School student, "suffered a gunshot injury as a result of a robbery" that took place near his home Sunday. 

The teen has "life altering implications such as spinal, lung, esophagus and shoulder traumatic injuries, as well as, paralysis of his lower extremities. The plan is to have him transferred to a rehab facility in the Boston area once he is stable," according to information posted on the site. 

Once Vermette returns home, he will need "extensive modifications" to "provide accessibility." 

"Thank you for helping Alex with his recovery and please keep him in your thoughts and prayers," family members said. 

A woman who identified herself as Vermette's aunt declined comment for this story, pointing to the active investigation. 

It remained unclear Wednesday what the motive for the teen's shooting was. 

On Monday night, a dark blue 2007 Honda Accord that was seen at the site of the shooting was recovered in Haverhill, police said. 

Police would not specify where in Haverhill the sedan was found. 

Police Chief Joseph Solomon praised the speedy efforts of investigators in the case. 

"It was excellent work by our Methuen police detectives and I also credit Haverhill, Lawrence and state police for all pitching in and helping us make a resolution so quickly," he said. 

"This is another great example of Merrimack Valley law enforcement agencies coming together," Solomon added.
