TARRYTOWN, N.Y. (AP) _ A man who routinely took target practice in the wooded area behind his house mistook his mother for a deer when he shot her while she was pruning a tree, police said Wednesday.

Takeko Hose, 47, was reported in critical condition at Phelps Memorial Hospital.

Her son, David Joseph Isamu Hose, 19, fired two shots from a .22-caliber rifle into her chest Tuesday evening, said police Lt. Andrew Kelleher of Greenburgh. Tarrytown, a New York City suburb on the Hudson River, is in Greenburgh.

Kelleher said it is illegal to fire a weapon in the neighborhood, but an investigation showed that Hose routinely took target practice or shot at game in the woods behind his house. Police said an investigation was continuing.
