Uncertain Dates

The Administrator's Birth

Pedro Martin's Birth

Esmeralda's Birth

Ivan's Birth

Leslie's Parent's Death

Arnold Brown's Death

Detective Arnold Brown was lobotomized by Ruvik after apparently acquiring significant evidence regarding related cases, though was dispatched before he could make it to the precinct. Whether or not he was captured in late 2011, before Ruvik was abducted by MOBIUS, or late 2014, possibly being one of the officers on-scene at Beacon Mental Hospital shortly before Marcelo Jimenez is unknown. While it would seem more likely that he was killed in late 2011, his body is strangely seen in STEM in 2014, though if he arrived in 2014, it would be unlikely that information regarding his possession of evidence regarding said case could be gathered before he was subsequently pulled into STEM.
