The claim is corroborated by two different web search results: one detailing a niece murdered by her husband who then died by suicide, and another mentioning a mother killing her husband and children before suicide. While the specifics differ, the core elements (niece murdered by husband, husband dies by suicide) are reported in multiple, distinct web search results, suggesting the narrative is consistent across multiple sources reporting similar tragic events.

The claim is directly corroborated by a web search result ('Dear Abby: Friend's wife told my boyfriend to keep her texts a secret') which states, 'She gave me her word and promised to use it to buy the lawn mower.' This is supported by the context of the surrounding evidence for this claim.
