The claim specifies a time (4:30 p.m.) that is not corroborated by the provided web search results. The search results mention different times (9:30 p.m., or no specific time for the general custody). Since only one source provided a specific time, and it conflicts with the claim, it cannot be corroborated.

The provided web search results are general resources about police news and departments (Police1, Houston PD) and do not contain any statement from multiple independent sources confirming that 'Police stated there is no longer a threat to the public.'

Multiple web search results mention Northglenn police and incidents (e.g., memorial service, standoff on I-95, Jennifer Boynton incident). However, none of the sources explicitly confirm that a standoff with a man on a roof *prompted authorities to secure area schools on Tuesday afternoon*. The evidence is too fragmented to corroborate this specific sequence of events.

The web search results provide general definitions for 'incident' and information about subway lines (High Street station, IND Eighth Avenue Line). None of the sources confirm that 'The incident location is E. 114th Avenue and High Street.'

The web search results contain a specific time reference (e.g., 'Police were called to the residence around 1:30 p.m.' in the Denver7 snippet), but this time is not corroborated by any other independent source provided in the evidence set.

The web search results mention specific elementary schools (Malley Drive Elementary School, Hulstrom K-8), but none of the sources confirm that *all three* listed schools (Wyco Drive, Hulstrom, and Malley) are currently under a secured perimeter status.
