The claim attributes the statement that the suspect is in custody to Officer Shelbie Boyd. While multiple web search results mention Boyd's statements regarding the suspect, the specific confirmation that the suspect is in custody is presented as part of the initial reporting and lacks independent corroboration from multiple sources.

While the claim details specific numbers (four in serious condition, two non-life-threatening) and attributes it to a Tacoma Fire Department spokeswoman, the provided evidence only contains general web search results about the incident and does not independently corroborate these specific numbers from multiple sources or authoritative records. The specific details remain confined to the context of the original reporting.

The claim specifies the breakdown of the injured (five students including the suspect, and one security guard). While multiple web search results mention these groups, the precise count and classification (5 students including suspect, 1 security guard) are most strongly associated with the reporting from Officer Shelbie Boyd, and independent corroboration of this exact breakdown from multiple sources is not available.

The claim states that all injured people were in stable condition on Thursday night. While one web search result mentions that 'all the victims were in stable condition Friday morning,' this is a different day and does not provide independent corroboration for the specific timing (Thursday night) or the status of all injured people from multiple sources.
