 TAMPA ï¿½ A McDonaldï¿½s employee handed a manager a gun Tuesday afternoon and then left the Ybor City restaurant to visit an Amscot, a coworker said. 
  
 When the employee returned, Tampa police were waiting. They took him to headquarters to ask about the gun and were soon proclaiming optimism about the ongoing hunt for the Seminole Heights serial killer. 
  
 "We have the person down at headquarters and we are talking to them now," Police Chief Brian Dugan said at a hastily called news conference. "They are not under arrest and they are not in custody." 
  
 Dugan did not characterize the agencyï¿½s interest in the man. He did not say whether the man was believed to have direct or indirect knowledge of the killings, if any knowledge at all. 
  
 But, he added, "Yes, I believe this has to do with Seminole Heights." 
  
 Officers used crime scene tape to block off a red Ford Mustang parked near the McDonaldï¿½s. 
  
 Hillsborough County court records show that two people have had traffic tickets while driving that vehicle, including one who worked at the McDonaldï¿½s. He has no criminal record in Florida. 
  
 Late Tuesday, two police SUVs closed part of a Sulphur Springs street where the manï¿½s family owns a boarded up house. Additional officers arrived as the night went on. 
  
 "Itï¿½s very early in the investigation," Dugan said at the news conference. "This person might be completely innocent," he said. "Iï¿½m optimistic on this one, but only time will tell. We have a lot of work to do. Itï¿½s very important that people still use caution, stay together when youï¿½re outside and be careful out there. Itï¿½s still very early and when we have more information, I will release it." 
  
 Tampa police spokesman Steve Hegarty cautioned news agencies not to jump to conclusions. 
  
 Dugan said police received over 5,000 tips, and theyï¿½re treating this one like any other. 
  
 Heï¿½s optimistic, he said, because of "the way things are progressing." 
  
 "Weï¿½ve had that before and unfortunately, itï¿½s led to nothing," Dugan said. "Iï¿½m guarded because Iï¿½ve been on this road before. Itï¿½s day 51 that weï¿½ve been doing this. Itï¿½s been two weeks since Ronald Felton was murdered. Itï¿½s been a long time for the families and the cops and so Iï¿½m guarded on the whole thing but Iï¿½m very optimistic. 
  
 "Thereï¿½s a lot to go through, a lot to sift through and itï¿½s going to take many things to fall in line." 
  
 Gail Rogers, who has worked at the McDonaldï¿½s for four years, said the employee police took in for questioning is in his 20s and was driving the red car, possibly his fatherï¿½s car. He has worked at the restaurant for just four months, she said. 
  
 Rogers said the man walked into the restaurant wearing his McDonaldï¿½s uniform and gave the manager a loaded 9mm handgun and asked him to hold it for him. Then the man walked to Amscot to get a payday loan, Rogers said. She does not know if he was working that day. 
  
 The manager didnï¿½t know what to do with the gun. Rogers said she huddled with the manager and said she told him to alert an officer inside the restaurant. A female officer was sitting there doing paperwork. 
  
 The manager told the officer about the gun. The officer called for backup and the employee was approached by Tampa police as he walked back into the McDonaldï¿½s parking lot.

 As word of the police activity spread, one victimï¿½s relative came to the McDonaldï¿½s. 
  
 "I just want to see whatï¿½s going on," said Casimar Naiboa, whose son, Anthony, 20, was killed Oct. 19. 
  
 "I want to know what is happening. I want to see this guy behind bars." 
  
 Naiboa expressed cautious optimism. 
  
 "You are excited, but donï¿½t want to be disappointed," he said. 
  
 Bettie McDaniels, the aunt of murder victim Benjamin Mitchell, said she is "waiting for police to say they really got him" before making any major statement. 
  
 "I hope it is him, but I am waiting to see," said McDaniels, whose nephew, killed Oct. 9, was the first of the four victims. 
  
 "I just hope it is the lordï¿½s will that they catch him," she said. 
  
 Kenny Hoffa, father of murder victim Monica Hoffa, 32, said he had spoken with Dugan and Det. Austin Hill and that they told him they were "optimistic" that the man picked up at McDonaldï¿½s is connected to the killing of his daughter. 
  
 "I have faith in Tampa police and Chief Dugan," said Hoffa, 52. "I am just going to wait and see what they have to say." 
  
 "I am nervous, and I really, I want this to be the end of this, " he said. "It is like riding a roller coaster right before you go over the edge and you feel your stomach raise up in your face."

 - As reports circulated that Tampa police were investigating a tip in the search for a possible serial killer in Southeast Seminole Heights Tuesday, neighbors in that community continued their efforts to try to make their streets safer. 
  
 Neighbors organized a community-wide initiative called Light the Heights, which is aimed at collected as many Christmas lights as possible. 
  
 The idea is simple: the brighter the neighborhood, the safer it is. 
  
 "The initiative is to light every single house in Seminole Heights," said Kelly Dempsey the owner of Southern Brewing and Winemaking. 
  
 Dempsey is among the business owners who have offered their stores as drop-off locations for donated lights. 
  
 This weekend, organizers plan to go out into the community and decorate as many homes as possible to keep their community bright. 
  
 "The more people who are here, the more vibrant it is, the more it intimidates any future events from happening," Dempsey said. 
  
 "I feel terribly for the families that were been directly impacted. But for the rest of us, it's kind of like we need to keep our community going," added Bob Fiallo, who helped organize the effort, adding one of the main goals is "to keep Christmas going. Don't let people get into a bunker mentality." 
  
 Neighbors have been coming together to think of new ways to make their community safer after someone murdered four people in five weeks beginning in early October. 
  
 People from throughout Tampa Bay have been driving out to Seminole Heights this week to donate their unused lights. 
  
 "I saw that there was a need here and the timing was right," said Dan Szlag, who drove in from San Antonio in Pasco County, adding the murders hit home for him. "[The victims are] just completely and totally innocent folks, just going about, minding their own business and being attacked brutally." 
  
 "They need them here more than I do," said Bryan Chaffee, after donated a box of lights. "This could be our neighborhood. We could be going through this kind of angst and anxiety."

Police in Florida may have just caught an enormous break in the hunt for a serial killer in the Seminole Heights neighborhood. A McDonald's employee is currently being questioned, and while cops stressed that no arrests have been made, they also sounded hopeful that they were close to catching the killer who has fatally shot four people over the last two months. “I’m optimistic about this one," said Tampa police chief Brian Dugan, per WFTV. But, he added, “We have to be very careful what we release because this person might be completely innocent.” The development began when an unidentified employee of a McDonald's in Ybor City handed a manager a loaded handgun and asked him to hold it while the employee went out to get a payday loan, reports the Tampa Bay Times. The manager talked the situation over with another employee, then decided to inform a police officer who just happened to be in the restaurant doing paperwork. The officer called for backup, and police were waiting for the employee when he returned. They took him in for questioning, and soon enough, the police chief called a news conference to talk about the possible break in the case. Police blocked off the employee's red Mustang in the restaurant's parking lot, and the Tampa Bay Times reports that two people have been issued tickets in regard to the car: Howell E. Donaldson, 52, and Howell Emanuel Donaldson III, 24. Another McDonald's employee said the person taken in for questioning was in his 20s and had been driving his father's car. One sign of how the killings have shaken the neighborhood: a push to light up the night with Christmas lights, per Fox 13.
