HOLLISTON, Mass. -- Holliston police used GPS technology to track flowers stolen from a child's grave three years in a row on Mother's Day, Boston TV station WCVB reported.

The flower basket was left by a mother at her son's grave. It had been stolen the past two years, but this year, the thief left with more than just flowers.

Police put a GPS transmitter inside the flower basket and tracked it to a house in Medway, where police said a man admitted to stealing the flowers to give to his sister-in-law.

Richard Guyette told police it was the first time he had taken the flowers.

"The same one in three years in a row is just remarkably poor coincidence on his part, or he knows something about it," Holliston Acting Police Chief Kevin Edison said.

Guyette was due to appear in court on charges of larceny and felony vandalism of a grave.

The recovery of the flower basket was a relief to Kevin Muzzy's parents, particularly his mother.

"We go there every day. We go up and pray for him and everything, and when you lose something like that, it's terrible, it's brutal," said Richard Muzzy, Kevin's father. "I think she knows now that she can put something up there and, hopefully, it's going to stay where she puts it."

Edison said the couple's son was killed in a motorcycle accident "at a very young age."

"For her, on Mother's Day, all she had now was to go down to the gravesite," he said.
