Oh yes. If this is the same man that attacked a woman near the tennis courts, and murdered Morgan Harrington, then this man intentionally harms people.
If this man approached a drunk 18 year old, seduced her with more alcohol, and invited her into his car, he intentionally harmed her.
With all due respect, we don't know that ANY of that is true at this point.
1. We don't know that he attacked a woman near the tennis courts. (We actually have zero indication that he did.)
2. We don't know that he murdered MH. (Again, we have zero indication that this is true.)
3. We don't know that he approached a drunk 18 year old. (As we don't know whether she was drunk, even if we assume that he was the one that approached her, as opposed to the other way around.)
4. We don't know that he seduced her with alcohol. (Or with anything else, for that matter.)
5. And we don't know that he invited her into his car. (And even if we assume this, it doesn't suggest harm in and of itself.)
Like Claudia said: "Anything is possible at this point." While that could include all five of the above being true, it is just as likely that an accidental overdose occurred.
IMO, the narrative that is being created of this young, naive female, incapable of any agency in her own decisions, doesn't reflect my own experiences as an 18-year-old college student. If we view HG as this helpless child, we ignore an entire range of scenarios, which ultimately reduces the likelihood of finding HG. (I do want to clarify that in raising the issue of HG's agency or decision-making, I am in no way, shape, or form judging/blaming/etc. I instead raise the issue because that agency and those decisions could give us important clues to her whereabouts.)
