Tampa, Fla. Terri Schiavo, the severely brain-damaged woman at the center of a long-running right-to-die court battle, was hospitalized briefly after nursing home workers found what appeared to be needle marks on her arms, a lawyer for her husband said.
However, tests found no unauthorized drugs or other substances in her blood.
Police were investigating.
Four puncture wounds were found on one arm and one was found on the other arm, said attorney George Felos, who represents Michael Schiavo.
He said the wounds, which appeared to have been caused by a hypodermic needle, were discovered after a 45-minute visit Monday by her parents, Bob and Mary Schindler, who have been fighting Michael Schiavo's efforts to remove his wife's feeding tube. Schiavo maintains that his wife would not have wanted to be kept alive artificially.
A purple needle cap was found in Terri Schiavo's gown in her room in a Clearwater nursing home, Felos said.
"It appears that someone was either trying to inject Terri Schiavo with something or withdraw fluids from her," Felos said.
Terri Schiavo, 40, was taken to a hospital emergency room, where toxicology tests were negative, Felos said.
She was returned to the nursing home.
Her father, Bob Schindler, told WTSP-TV in Tampa that nothing was wrong with his daughter when he left the nursing home.
He also said that he did not insert a needle into his daughter's arms.
