The tagging for CSD actually had some basis as the assertion of notability was not properly sourced However it could and now has been adderssed The Slovenia wiki article while interesting is itself unsourced  but this is likely due to they have entirely different considerations for inclusion than enWiki So that link has now been moved per WPLAYOUT Its available to readers but cannot be used to assert or confirm notability on enWiki And naturally being a mass murderer is pretty much a given for notability per guideline in enWiki it must be properly sourced The original single ref was to usergenerated content on a nonreliable source and so did not meet criteria A much more suitable and definitely Reliable Source has been added so the questionable source can either be removed or ignored Further I have tagged the article for expansion and requested the attention of experts
