( CNN ) -- As Tracy Ocasio 's 28th birthday came and went last week , her mother remained hopeful that she would soon get answers about the young Florida woman 's disappearance nearly three months ago . Tracy Ocasio disappeared after watching a ball game with friends at an Orlando , Florida , sports bar . Police have a person of interest in custody on unrelated charges , but they still do n't have the full story , said Detective Mark Olson of the Ocoee Police Department near Orlando . In honor of Ocasio 's birthday , her family increased the reward for information on her disappearance to $ 20,000 . Elizabeth Ocasio said she last spoke with her daughter about 8:30 p.m. May 26 . Tracy Ocasio said she planned to come home that night after watching a televised basketball game with friends at the Florida Tap Room , a popular sports bar in Orlando . When Ocasio did n't come home that night , her mother said she assumed she 'd decided to stay at a friend 's house . She often stayed with the friend when she was too tired to drive home . At 6:30 the next morning , Elizabeth Ocasio sent a text message to her daughter : `` Where are you ? '' She did not receive a response , she said , so she called her daughter 's cell phone again two hours later . The phone rang a few times and then went to voice mail . She tried calling Ocasio several more times that day , and each time , the call went to voice mail . `` I was worried , but I still did not imagine that anything terrible could have happened , '' Elizabeth Ocasio said . Panic set in when she received a call from police on the afternoon of May 27 . They 'd found Tracy Ocasio 's car in a rundown neighborhood three miles from the Ocasio home . The car was parked on private property , and the residents had called to have it towed . `` When I got there , I knew something did n't make sense . Tracy would never go to such a neighborhood by herself , '' Elizabeth Ocasio told CNN . She found her daughter 's purse in the car , but her ID , cell phone and car keys were missing . By 7 p.m. , Tracy Ocasio was officially reported missing and a county-wide search was under way . It lasted for weeks . `` We searched bodies of water and heavily wooded areas , '' Olson said , `` and we continue to search based on tips we receive . '' The investigation led detectives to James Hataway , 28 , who is considered a person of interest because a Tap Room surveillance video shows him leaving the bar with Tracy Ocasio , Olson said . A spokesman said the Orange County Public Defender 's Office would have no comment . Police questioned Hataway for 11 hours over two days . He told investigators that Ocasio had given him a ride home from the bar that night , Olson said . Hataway told police that he did n't see Ocasio after she dropped him off . His home was just 200 yards from where Ocasio 's car was found , police said . During questioning , Hataway took a polygraph test , which police said showed some discrepancies , Olson said . Police brought bloodhounds to where Ocasio 's car was found , but the dogs did n't hit on her scent , leading police to believe she was n't the one who parked her car there . Police also say no forensic evidence was found to suggest Ocasio was injured or killed inside her car . Police are holding Hataway on unrelated charges at the Orange County Jail . He is charged with aggravated battery , robbery and false imprisonment stemming from an incident in neighboring Seminole County in August 2008 . A young woman said she gave him a ride home one night . She said he attacked her and tried to break her neck , but she fought back . She 'd reported the assault when it happened but only later were police able to identify Hataway as the alleged assailant . Hataway remains in custody on those charges with bail set at $ 250,000 . He has not pled . Shortly after his interrogation in the Ocasio case , the public defender 's office took Hataway 's case , and he stopped talking . Hataway has not been named a suspect and has not been charged in the Ocasio case . Police and family urge anyone with information that can lead to the arrest of the person responsible for Ocasio 's disappearance to call the tip line at 1-800-423-TIPS . A $ 20,000 reward is offered .
