SPARKS, Nev. (AP) — Police stormed a Nevada apartment after a standoff and found a Nevada couple who appeared as ghost hunters in the reality television show "Ghost Adventures." 
 
 Mark and Debby Constantino were found dead Tuesday in a barricaded Sparks apartment. Officials weren't releasing a cause of death. 
 
 The couple was featured in recent years on the Travel Channel's series, including episodes shot at the Mustang Ranch brothel east of Reno, the Goldfield Hotel and the Market Street Cinema in San Francisco. 
 
 A SWAT team responding to a hostage situation found their bodies when officers stormed their adult daughter's apartment near Sparks High School following an hours-long standoff on Tuesday. 
 
 Mark Constantino shot at officers who approached the door of the Sparks apartment, but they did not return fire, police said. 
 
 "The subjects involved in this incident were not shot at or injured by gunfire from any law enforcement personnel," Sparks police Lt. Rocky Triplett said in an email Wednesday to The Associated Press. 
 
 Washoe District Court records show Debby Constantino obtained a restraining order that was served on her estranged husband last week and the two were scheduled to appear in court in December regarding their pending divorce. 
 
 KTVN-TV in Reno, which videotaped them during a ghost adventure in 2007, first reported late Tuesday they were paranormal investigators. 
 
 Tuesday's incidents began at 6:30 a.m. when Reno police received a call of a man found dead at a home in northwest Reno where Debby Constantino had been living. She was missing. 
 
 Police say Mark Constantino was a suspect in that death. 
 
 Without naming her at the time, Reno police Lt. William Rulla told the Reno Gazette-Journal she had been a victim in an earlier kidnapping and domestic incident involving Mark Constantino, and that officers tracking her cellphone located her inside the Sparks apartment with her estranged husband. 
 
 Officers heard several shots fired when they knocked on the apartment door and heard a man yelling at police to leave. The suspect told the officers "give me 15 minutes to gather my thoughts or I'll kill her," Reno Deputy Police Chief Tom Robinson told the newspaper. 
 
 One officer was taken to a hospital after he was hurt by broken glass when police used explosives to open the door. 
 
 The Constantinos lectured at paranormal conferences around the country and maintained a Web site, www.spirit-speak.com. ||||| The couple were found inside their daughter’s apartment at 1100 15th Street, near Sparks High School. 
 
 SWAT teams from both Reno and Sparks police surrounded the Courtside Gardens Apartment, evacuated the complex and put it on lockdown. 
 
 The incident started at 6:30 a.m. when Reno police received a call of a man found dead at a home in the 2300 block of Escalera Court in northwest Reno. 
 
 A woman arrived at the residence to find her roommate dead inside, Reno Police Lt. William Rulla said. As they were investigating, they learned that another roommate, Debbie Constantino, was missing. 
 
 Officers tracked her cellphone and found her inside the apartment in Sparks with her estranged husband. 
 
 Rulla said she was previously a victim in a kidnapping and domestic incident with her husband. 
 
 Upon arriving at the apartment, officers knocked on the door and heard several shots fired, said Deputy Chief Tom Robinson, of the Reno Police Department, in an earlier interview. 
 
 The suspect told police "give me 15 minutes to gather my thoughts or I'll kill her," Robinson said. 
 
 Officers said they heard a man yelling at police to leave. Police began negotiating with the suspect, but officers eventually used explosives to blow the door open and found the couple dead inside. 
 
 Police did not say how they were killed or what kind of gun was used. 
 
 Sparks High School was put on lockdown as a precaution, but eventually released at the normal 2:35 p.m. time. 
 
 Police weren't searching for other suspects, but haven’t ruled out anything, Rulla said. 
 
 The name of the male roommate found in the northwest Reno home was not immediately released.

NBC's Mark Potter reports 
 
 SWAT officers shot and killed a gunman early Saturday after he killed six people, ending an hours-long standoff near Miami, Fla., police said. 
 
 Two people were rescued alive and unharmed from an apartment building where they were being held hostage, Hialeah police spokesman Sgt. Eddie Rodriguez told NBC News.

 Police identified the shooter as Pedro Vargas, 42, at a press conference on Saturday, according to NBC Miami. 
 
 The victims were identified as Italo Pisciotti, 79; Camira Pisciotti, 69; Carlos Javier Gavilanes, 33; Patricio Simono, 64; Merly S. Niebles, 51, and Priscilla Perez, 17. 
 
 Perez's family members were left in shock following the harrowing news. The teenager was an incoming senior at American Christian School with aspirations of becoming a pediatrician like her father, who lives in the Dominican Republic, her grandmother, Gladys Perez, told NBC Miami. 
 
 "She had just started to live," Gladys Perez said in Spanish. 
 
 Cousin Jovanny Perez, also 17, told NBC Miami he was trying to make sense of the killing. 
 
 "It's like a hole in the heart," he said. "Everything's a bit darker." 
 
 The SWAT team found the gunman barricaded on the fourth floor of the building, where they killed him and saved the two hostages.

 The building manager and her husband were found dead in a hallway and three others, two females and one male, were found in one of the apartments, Rodriguez said. Another man was found dead in the lobby of a building across the street. 
 
 "This is one of the worst shootings we've probably had ever in Hialeah," police spokesman Carl Zogby told NBC Miami. 
 
 Fire rescue crews were first called to the scene, where Vargas had lit his apartment on fire by burning $10,000 in cash, according to NBC Miami. The responders evacuated the apartment complex and shut down several surrounding streets. 
 
 Several hours into the standoff with police, Vargas forced his way into an apartment and held Zoeb Nek and Sarrida Nek captive, according to NBC Miami. 
 
 Negotiators were talking to the gunman and police sent a robot onto the scene, but eventually officers stormed in and fatally shot Vargas. The gunman still had several rounds of ammunition in his 9mm pistol when he was killed, Zogby said. 
 
 “The end result: seven people have lost their lives in this incident, six innocent victims and the one shooter,” Zogby told the station. “Now starts the investigation, how and why this happened.” 
 
 Italo Pisciotti, and Camira Pisciotti owned the building and were shot by the gunman when they went to his door, Zogby said. 
 
 The couple’s daughter described the horrific scene.

 A young woman told NBC Miami that two of the victims of the shooting were her parents. 
 
 “I guess there was an altercation and the person opened fire on both of them. My mom was dead the moment that she was shot and my dad still had a pulse when I got to him,” Pisciotti told NBC Miami. 
 
 One of the victims appeared to have been shot at across the street from the main scene, police said, when the gunman opened fire from a balcony. 
 
 “From up there, he was able to shoot at people across the street, catching this one man who was just walking into his apartment,” Rodriguez told the Miami Herald. 
 
 Officials said Vargas' mother, who lived in the apartment with him, was home when her son began shooting. Police were able to get to her and escort her from the area while the shooting was going on. 
 
 "He was a good son," said Ester Lazcano, who lived on the Vargas’ floor. "He'd take her in the morning to run errands." 
 
 Miriam Valdes, a woman who was often in the building, had a different impression of Vargas however, and said he would get into fights and yell at his mother. "He was a very abusive person. He didn't have any friends there," said Valdes. 
 
 Police said the gunman had no criminal record, bought his handgun legally and had a concealed weapons permit.

– A pair of ghost hunters were found dead in a Nevada apartment yesterday following an hours-long standoff with SWAT teams in what is likely a domestic-violence incident, the AP reports. They were identified by police as paranormal investigators Mark and Debby Constantino, who had made numerous appearances on Travel Channel's Ghost Adventures, according to the Reno Gazette-Journal. The AP reports the couple had a history of domestic incidents, and Debby had taken a restraining order out against Mark last week. They were scheduled to appear in court in December over their pending divorce. Police received a call after Debby's male roommate was found dead in their home yesterday morning, the Gazette-Journal reports. Debby was missing, and police tracked her cellphone to the apartment of her and Mark's adult daughter. When officers knocked on the door, they heard shots fired and a man saying, "Give me 15 minutes to gather my thoughts or I'll kill her." After failed attempts to negotiate, police blew open the apartment door and found Mark and Debby dead inside. Police have so far not released a cause of death, according to the AP. Mark is suspected in the murder of Debby's unidentified roommate. (These 79 celebrities have been charged with domestic abuse.)
