The sister of Sen. Andrew Maynard, D-Stonington, said Tuesday that the injuries he suffered in an early morning fall Monday are “non-life threatening,” and he is in serious, but stable condition.

In the family’s first public statement since Maynard’s fall, his sister, Denise Mahoney, offered no specifics on the nature of his injuries, nor did she give a prognosis on his ability to resume campaigning for re-election.

But Mahoney said in a statement released by the Senate majority office that her brother was “resting comfortably with family and friends by his side.” She thanked the public for an “outpouring of support.”

“We request that our privacy be respected at this time and we will update you on Andrew’s condition as more information is available,” she said. “Any additional update on Andrew’s condition will come through the Senate Democrats Office.”

Stonington police said they were called at 2:39 a.m. Monday by a neighbor who reported that Maynard had fallen from a “significant height” on the exterior stairs at his residence.

He was taken to Westerly Hospital in Westerly, R.I., and then transferred to Rhode Island Hospital, a regional trauma center in Providence. Maynard’s district is on the Rhode Island border.
