Ok, based on all the research I have done, I think the man responsible for this may be German Medina. I will provide the evidence that leads me to believe this.

This man is being charged with the murder of his girlfriend and has since been missing. Her body has been found. I'm not sure the exact date but it was early September. In this link above, look at this man's picture and how closely it matches #1. Also, the Ketner lake incident was described as possible hispanic male. 1900 block of Paris Street. Quote from neighbor..
"He always carried a long knife on him," the neighbor told the station. "He always kind of gave me a weird vibe. When I found out what happened, it made the hairs on the back of my neck stand up."
She also recalled an incident from a few months back, in which Medina reportedly walked past her only to return and invade her personal space -- something he repeated three times, until she called her fiance outside.

The attempted bar abduction on video. The driver, described as a white, possibly Hispanic, clean-cut male, 22 to 30 years of age. The second man is described as white, possibly Hispanic, 5 feet 6 to 5 feet 9 inches tall, 22 to 30 years of age, clean shaven, with short hair.

12 year old girl was inside house. Grandmother was outside. She came inside and the girl was missing. (5 minutes away from German medina's deceased girlfriends house) I don't know medina's former address and am still looking in to this.
There is currently a nationwide manhunt for this man. He lived with his two brothers in an apartment. There was more than one individual at the attempted bar abduction incident. I don't know if his brothers have disappeared too. If you look at the description of #1 and this man's picture it is strikingly similar. Everything, the mustache, goatee, height, nationality. Of course this could all be coincidence but this seems very odd to me. Can anyone link this man to any other descriptions in recent abduction attempts?
