ATTLEBORO -- It's been almost two weeks since 20year-old Andrew Miller collapsed while playing soccer at an indoor facility on Jefferson Boulevard in Warwick, R.I.

There was no collision with another player, no apparent cause.

Now, the South Attleboro native lies in a coma at the Cardiac Intensive Care Unit at Rhode Island Hospital, having been taken off of life support at his family's request.

In light of his steadily deteriorating condition, the family saw no other option.

`` It was just, a lot of medical terms. But all the signs were worsening,'' said mother Kim Miller, 9 Remington Road. `` We took him off Monday and he's still with us. It's a slow process, a painful process.'' Though teammates and members of the audience at the soccer game tried to revive Miller using CPR, initial attempts were unsuccessful, and Miller suffered permanent brain damage due to oxygen deprivation.

He arrived at the emergency room at Rhode Island Hospital on Sunday, March 12, in a coma, which he has remained in since.

As time passes, there's little left for family and friends to do but wait, and wonder.

`` There's no reason for it, it's just a one in a billion shot something like that could have happened,'' said close friend Bill Findlay, 22, of Plainville. `` Our whole group of friends was really, really close. We're just totally in shock, we can't believe it happened. It shouldn't have happened.''

Findlay described Miller as an energetic, active young adult who was `` always doing something,'' from playing sports to playing bass guitar.

`` He never drank, he never did anything like that. He didn't do any body building supplements. He didn't even take a vitamin, to be honest with you,'' he said.

By many accounts, before Miller's collapse, there were no telltale signs of any physical problem, no inklings that something might have been wrong.

A graduate of Attleboro High School, Miller played soccer there all four years, spending the final two on the varsity team, and was an avid gymnast, serving as captain of the gymnastics team his senior year.

`` I've known him since he was a little guy playing on youth teams in town,'' said Peter Pereira, head coach of the boys' varsity soccer team at Attleboro High School. `` He was a kid who was in really decent shape, he didn't have any fat on him, something like this happens, it's shocking.''

`` Right now everybody's just waiting to see what's going to happen. The waiting is awful,'' he said. After his high school days, Miller played on a coed indoor soccer league, his mother said, the same league he was playing with when he collapsed, and had planned to join CCRI's soccer team in the fall.

Beyond just being an active sports enthusiast, Miller was described as a popular kid, a good friend, a hard worker.

Kim Miller said there has been a huge outpouring of support from friends and family.

Pereira said students at the high school have been approaching him on a regular basis, wondering what's going to happen to Miller.

`` He had a lot of friends, he's not the rah-rah type, he was calm and collected most of the time,'' Pereira said. `` I keep saying `was' as if it's the past tense. It's awful.''

While family and friends are left to comprehend the seemingly incomprehensible, doctors are still trying to uncover the cause of Miller's collapse.

`` They're not sure. No drugs, no alcohol were involved, he's always been a healthy kid,'' Kim Miller said.

Doctors have suggested that Miller may have suffered from Brugada's syndrome, an illness that causes interference with the electric signals that control the beating of the heart, and one of the main causes of sudden death in young adults.

But there hasn't been a definitive answer.

Findlay is still clinging to a positive outlook.

`` We're all still hoping for the best, because honestly we don't want to lose him,'' he said.

Kim Miller said her son had a bright future ahead of him -- he was taking fire science courses at CCRI, where he was a freshman, and was planning on taking the civil service exam in the spring and taking paramedic courses in the summer.

He wanted to become a firefighter like his father Gerald, who currently serves on the Boston fire department, she said.

Now, Miller's family is trying to face the fact that that future may never be realized.

`` There's no words that can describe it. I think most people right now are numb,'' Kim Miller said. `` It's been overwhelming.''
