Cards, flowers, letters and other messages of support have been pouring in for the family of a guard shot in her booth at a busy Canada-U.S. border crossing and the guard's family says they are very grateful.

Lori Bowcock's family said in a statement Thursday she is doing well and is expected to make a full recovery.

"We are happy to report that her positive outlook and sense of humour are shining through," the statement said.

"Even after she was wounded, Lori's first concern was for the safety of her fellow officers and the public that she has dedicated her career to protect."

Well-wishes have been sent from U.S. and Canadian border guards, the U.S. consulate, Washington Gov. Christine Gregoire, Surrey Mayor Diane Watts and former colleagues at the Ontario Provincial Police.

"Lori has read each of these messages of support and is deeply moved by the thoughtfulness and care expressed," the statement said.

The Bowcock family also extended their condolences to the family and friends of Andrew Crews, who killed himself immediately after shooting Bowcock in the neck.

The shooting at the Peace Arch border crossing, one of Canada's busiest, shut down the border in both directions for most of a day.

Crews was living in Washington and his stepfather says he sent his mother a text before the shooting to say he loved her and was sorry.

Danny Lupinek of Henderson, Nev., said his stepson didn't indicate what he meant by that text and family members were unable to reach him later.

Police have not publicly speculated on what motivated the shooting.

"The current evidence clearly indicates that prior to taking his own life, Mr. Crews deliberately fired at the victim," RCMP Supt. Kevin Hackett, who is in charge of the region's homicide unit, said in a statement.

"There is no evidence, however, to suggest the victim was specifically targeted."

Bowcock had worked as a civilian dispatcher with the Ontario Provincial Police until this past spring. She started work at the B.C. border crossing three months ago.
