I'm not convinced that portion of the publication can be understood clearly.
"Bertolino said there are inaccuracies with the report and said the source claiming to be close to the Laundrie family is not. "I don't know what her motives are."
What is "the report"? The way this is worded, and it's standalone positioning within the whole piece, makes it suspect to me. Even the combination of the two sentences in the particular paragraph can be questioned. Is the "her" actually referencing the "source"? Could be. But, then again, it could be a poor (or strategic) phrasing pattern.
Good point. It's hard to know if it's poor composition by the writer, a quote taken partially out of context, or something else. Among other things, the Sun isn't known for the skill of its writers.
