EAST PENNSBORO TOWNSHIP - The Camp Hill-area man who authorities say shot his wife and then himself had, just a day earlier, responded to a call for help in his community.

James Grundon, 55, was a firefighter and paramedic with the West Shore Bureau of Fire, which has stations in both Lemoyne and Wormleysburg. On Saturday night, he responded to a fire at Cafe Uovo.

The next day, authorities say, Grundon shot his wife, Sue E. Grundon, 54, before taking his own life on Sunday. Sue Grundon died a short time later after she was transported to an area hospital, Cumberland County Coroner Charley Hall said this morning.

Hall confirmed Grundon was a firefighter and paramedic with the West Shore Bureau of Fire. But right now, the fire department isn't ready to talk about him or Sunday's events.

"The department has been hit very hard by this tragedy," Fire Chief Tim Mulhollan said, adding out of respect for those involved, the department is not commenting further.

While investigators have been able to piece together what happened, the question is still "why did this happen?"

Hall said the motive is unknown at this time, but the East Pennsboro Township Police are still investigating.

A witness, who did not want to be identified, said Sunday she saw a man fire three times at a car as a woman was backing down the driveway, then fired once at close range from the driver's side window before heading back to the house.

The home of James and Sue Grundon on the 800 block of Country Club Road.

As that witness rendered first aid, she said she heard another shot from the house, presumably James Grundon ending his own life.

Their home sits in a seemingly peaceful neighborhood of green grass, nice homes and plenty of shade from the sun on the 800 block of Country Club Road. It was quiet there this morning, too, save the sound of a distant lawnmower.

One neighbor, who did not want to be identified, knew the Grundons casually.

"They were a nice couple. It's very tragic," she said. "I feel for the families."

They liked their house and were nice neighbors, she said, but did not wish to get into many specifics about them.

The Grundons lived in a brick ranch-style home with an attached garage and American flags all around. A decorative bone in the front yard kindly indicates the house is "protected by Gunner," presumably the black German shepherd prominently featured in Sue Grundon's Facebook page.

And on that Facebook page, she had just updated her profile picture - a smiling, carefree selfie.

The comments under that recent post take a quick turn, from friends saying "Beautiful!" to "RIP my dear friend."

James Grundon's page was last updated June 5 with a photo of him in the dress blues of a fireman's uniform, another man in a uniform and a young boy in front of a firetruck. One friend commented "Nice picture of hopefully 3 generation of firefighters."
