NEW YORK (CBSNewYork) -- A couple is recovering at a hospital after being shot while standing outside of their Staten Island home.

Now, police are looking for the shooter.

As CBS2's Emily Smith reported, the longtime home of a happily married couple became a crime scene Sunday when 63-year-old Pat Schmidt and her 71-year-old husband Edward fell to the ground on their front steps -- shot in broad daylight.

"I heard one gun shot go off in that direction over near the park area...and then I heard at least 10 to 12 go off afterward," said neighbor Ronald Allen. "I ran to the window and saw a lot of people running."

"At first I thought they were fire crackers so I wasn't thinking too much of it. But then I heard a lot more," said Jesse Allen.

The shooting happened around 5:30 p.m. at 224 Jersey St. Pat was struck by a bullet in the arm, Edward in his torso.

"When I came down, they said Miss Pat got hit and I said 'Oh my God, her of all people?'" said Allen.

Witnesses told police the shots came from a group riding dirt bikes. Authorities do not believe the shooter intended to target the couple, Smith reported.

But other than that, police do not have any suspects or a motive.

Neighbors said the Schmidts enjoy gardening, their children and grandchildren.

"Miss Pat, she to me, is a pillar of the community and pretty much a mother figure," said Allen.

The couple is being treated at Richmond University Medical Center. Their injuries are serious but both are expected to survive.

Police are going door-to-door in the neighborhood hoping to find out more about the shooting.
