Orlando Sentinel and Ty Smith

Mateen: Van Horn, who lost three friends in the shooting, says he met Mateen once and the two talked about the latter ex-wife, before friends pulled the 71-year-old away because "they thought Mateen was a strange person." Ty Smith, a Pulse patron, also told the Orlando Sentinel that he saw Mateen inside the nightclub at least a dozen times, recalling, "sometimes he would go over in the corner and sit and drink by himself, and other times he would get so drunk he was loud and belligerent, according to CTV. Questions are now being raised about Mateen sexuality as a possible factor in the attack. QUESTIONS ABOUT SEXUALITY In an interview with The Associated Press late Monday, Jim Van Horn spoke to reporters about Mateen, who he claimed was a regular at Pulse nightclub who would try to pick up men. Reports claim he may have been on the popular gay dating app Grindr. When he first contacted me, he was saying, like asking, what clubs, in his words, what clubs are popping and things of that sort, and what are good places are to go, says West. One man, Kevin West, claims Mateen contacted him via the app in an interview with an ABC station. (www.immigrantscanada.com). As reported in the news.
