TULSA, Okla. (AP) _ A 17-year-old newspaper carrier who was shot in the head while delivering newspapers three weeks ago is in serious condition after suffering seizures, hospital officials said today.

Keith Hurn was admitted to the pediatric intensive care unit of St. Francis Hospital on Thursday.

The boy and his father were delivering newspapers June 21 when their car was struck by shotgun blasts. One of the pellets struck the boy in the head and penetrated to his brain.

Homer Hubbard has been charged in the case with shooting with intent to kill.

Keith had taken over the newspaper route temporarily to earn extra money for a Tulsa Youth Symphony trip to London that begins July 20.

''Obviously, he's not going on his trip,'' said his mother, Anna Hurn.

Mrs. Hurn said her son had been making good progress before he had his first seizure last week. He had been released from the hospital July 2.

She said doctors expect the boy to make a complete recovery, but she said they also warned that seizures are common in patients who have brain injuries.

Keith plays violin for the symphony and is a member of the Union School classical music symphony. The shooting received national attention and about $1,000 in donations was received, said Mrs. Hurn.

She said some letters have been sent by elderly people ''who can hardly write and yet they're thinking of this young man,'' she said. ''It's been so uplifting.''
