 Jill Halliburton Su lived a comfortable life.The wife of a prominent professor and a relative of the founders of the billion-dollar Halliburton oil empire, Su lived in an upscale mansion in a gated Florida community. In her spare time, she read to the blind and raised money for various charities.But everything changed Monday when Su, 59, was found dead in a bizarre murder mystery that is raising more questions than answers."She was always involved in helping others. She was the first person to volunteer for anything," says her friend Theresa Randolph, who she has known for more than a decade. "Just a very sweet, kind, giving woman."On Monday morning, Dr. Nan Yao Su, a professor of entomology at the University of Florida's Research and Education Center in Fort Lauderdale, tried to watch the live feed of his home's security cameras. When he was unable to see the feed, he called home. Receiving no answer, he called his adult son and asked him to check on the house.When the son arrived at the waterfront mansion, he found a chilling scene. A glass door had been broken; shards of glass covered the ground. At least one room had been ransacked. And worst of all, his mother was lying dead in a bathtub.The son called 911. "The initial call came in as a possible suicide," Davie Police Captain Dale Engle told ABC News , "but it became very evident that this was not a suicide, but in fact a homicide."How, exactly, she died remains a mystery. Reached by PEOPLE, police wouldn't comment on either the cause or manner of death.Both father and son were extensively questioned by police – and a police spokesman tells PEOPLE that they were both very cooperative and did not hire lawyers. At this point, neither are considered suspects, although police haven't ruled them out."I don't want to say that anybody's been ruled out as a suspect," Engle said. "At this time, this is a very active investigation."Friends don't think that Dr. Nan Yao Su could possibly be involved. "Theirs was a strong marriage," Randolph tells PEOPLE. "I can't imagine that he had anything to do with it."Police have searched the lake behind the family home and are asking neighbors to turn over their surveillance videos."This is a gated community. There's only one way in and out," Sgt. Edwin Smith, spokesman for the Davie Police Department, told reporters. "We would ask anybody in this neighborhood to contact us if they saw anything unusual."The death has left her loved ones reeling. "Everyone is devastated, just devastated," Randolph says. "It's going to take a long time for this to sink in." ||||| DAVIE (CBSMiami) – Amid a death investigation, authorities are getting a deeper look at the life of a woman killed in her Davie home. 
 
 Jill Halliburton Su volunteered at Insight For The Blind in Fort Lauderdale. She spent hundreds of hours working there over the past nine years, recording material donated to the blind. 
 
 Su was supposed to be there on Tuesday but no one knew the reason for her absence until news of her death emerged. 
 
 “She was so popular with everyone and would do whatever was needed either reading or monitoring recordings,” said Executive Director Mathew Corey. 
 
 Su inscribed the lettering on a donor wall leaving a lasting legacy. 
 
 “This is a family and the people here have a calling and no one did it better than Jill,” said Harry Sharp of Insight For the Blind.

 Su’s spacious home she shared with her husband, renowned entomologist Dr. Nan Yao Su, remains a crime scene. 
 
 Davie Police executed a search warrant and for a second day on Wednesday dive teams were scouring the lake behind the house. 
 
 “We don’t want to get into specifics of what they are looking for but we do think there is evidence connected to the crime,” said Davie Police Captain Dale Engle. 
 
 Police confirm a back glass door by the pool was smashed. Detectives are reviewing surveillance in the community and talking to everyone who knew Su.

 ||||| Police in Florida are investigating the mysterious murder of a woman found dead in her bathtub. 
 
 Jill Halliburton Su -- the wife of a prominent University of Florida professor -- was found dead Monday inside her Davie, Florida, home in Broward County. 
 
 The 59-year-old’s son discovered her body and called 911. Davie Police Captain Dale Engle said it didn’t take long for authorities to conclude that foul play was involved. 
 
 “The initial call came in as a possible suicide, but it became very evident that this was not a suicide, but in fact a homicide,” Engle said. 
 
 At this point, police aren’t saying how Halliburton Su died. 
 
 She was related to the founder of the billion-dollar Halliburton oil services empire -- and also volunteered, reading books for the blind. 
 
 Her husband, Dr. Nan Yao Su, a professor of entomology at the University of Florida’s Research and Education Center in Fort Lauderdale, was at work Monday, and said he called home when he couldn’t see his home surveillance cameras on his computer, police said. 
 
 He told his oldest son to check on the house, at which time the victim’s body was found. 
 
 Both father and son were questioned by police and, at this point, neither are considered suspects, Engle said. 
 
 “I don’t want to say anybody’s been ruled out as a suspect. At this time, this is a very active investigation,” he said. “We did find a door that was broken or the glass of a door that was broken.” 
 
 That broken glass suggests that the house could have been broken into, with a room reportedly ransacked. Police are now canvassing the gated neighborhood, looking at surveillance tapes and even diving into nearby canals for clues. 
 
 “We’re going door-to-door, literally speaking, with residents over there to see if anybody captured any evidence that we may be able to utilize in this investigation,” Engle said. ||||| Police continue investigation in Davie mother's murder Posted: Wednesday, September 10, 2014 12:17 PM EDT Updated: Friday, September 19, 2014 1:37 PM EDT 
 
 DAVIE, Fla. (WSVN) -- A Davie Police dive team continues to search for clues beneath the surface of a canal located behind the home where a South Florida mother's body was found. 
 
 Fifty-nine-year-old Jill Su's son found his mother dead at home, at 10327 S.W. 22nd Place, Monday. On Tuesday, Davie Police stepped up their search for answers, sending a dive team to search a canal behind the family's home. Tuesday night, a car was towed out of the West Ridge development, but police have not confirmed whether that the car is related to the murder. 
 
 Wednesday morning, dive teams from the Davie and Miami-Dade Police departments resumed searching for evidence in the canal. 
 
 Davie Police Capt. Dale Engle said they are using Miami-Dade Police's sonar equipment to search the canal's bottom. "Some of the equipment that Miami-Dade has access to, we feel, would be an advantage that we're looking for in this case," he said. 
 
 At the moment, officials have not yet released any details on how the victim died. Su's son and her husband, Dr. Nan Yao Su, an entomology professor at the University of Florida, have have been questioned by detectives. The couple had just come back from a vacation to Kuala Lumpur. 
 
 Su was set to return to her volunteer schedule at Insight for the Blind on Tuesday. "She was due in at 11:30 this morning," said Insight for the Blind studio director Harry Sharp, "and she didn't show up, and we thought, 'Well, you know, maybe she's still sleeping from her trip. She just got back.' We knew she was tired." 
 
 Su read books onto tape. She spent nine years volunteering. "Typically she'd either be reading or on the other side of the glass as a monitor, which is a volunteer engineer basically. They follow the magazine or the book that's being narrated and check for accuracy," said Matt Corey, CEO at Insight for the Blind. 
 
 Corey described Su as a woman who had a passion for life. "She was proud of her kids, and she talked about her husband a lot," Corey added. 
 
 Su's body was found in a bathtub at her home at around 2 p.m. Monday. A window inside the residence was broken. Moments later, as a pool cleaner was leaving the property, the victim's son ran outside the home. "It was the most craziest thing I've seen," said Ryan Madriz, the cleaner. "I see the kid open the door, and he's crying, screaming hysterically, and he's telling us, 'Don't leave, you can't leave,' so I ask him, 'What's wrong? What's going on?' and he said, 'Somebody broke into my house and killed my mom.'" 
 
 Madriz said that is when he realized the victim's son was covered in blood. "When he said those words, I was like, 'Are you serious?' and I looked down at him and his hands, his arms and his shirt are covered in blood," he said. 
 
 Police spent part of Tuesday and Wednesday going door to door talking to neighbors and searching for surveillance footage that could provide insight into Su's murder. "Our detectives continue canvassing the neighborhood for residents who have surveillance video that may have captured the suspect coming or going," said Engle. 
 
 Officials said cameras at the West Ridge development may be key in the investigation. Detectives have been going over video from the front gate. "As part of their investigation, of course, they've been at the front gate of the development, which has video going in and going out," said Davie Police spokesperson Ed Smith, "so they are doing the best that they can do to find anything that might've captured any information that can help us." 
 
 Investigators are trying to acquire surveillance video from inside Su's home. 
 
 By late Wednesday, police divers had wrapped their search of the canal, but did not say what, if anything, they may found inside. 
 
 If you have any information on this murder, call Broward County Crime Stoppers at 954-493-TIPS. Remember, you can always remain anonymous, and you may be eligible for a reward.
– Police in Florida's Broward County have a high-profile murder on their hands: Jill Halliburton Su, a 59-year-old relative of the founder of the oil services conglomerate, was found dead in a bathtub in her waterfront mansion in Davie this week, reports ABC News. Police have ruled it a homicide but haven't commented on the cause of death or named any suspects. Su is married to a prominent entomologist at the University of Florida, Nan Yao Su, who tells police that he grew alarmed while at work Monday afternoon when he could no longer see the live feed of his home's security cameras, reports People. He says he called his adult son to check on the house, and the son made the discovery and called 911. "The initial call came in as a possible suicide, but it became very evident that this was not a suicide, but in fact a homicide," says a police official. That it seemed like a suicide at first doesn't seem to jibe with what a pool cleaner tells WSVN: "I see the kid open the door, and he's crying, screaming hysterically, and he's telling us, 'Don't leave, you can't leave,' so I ask him, 'What's wrong? What's going on?' and he said, 'Somebody broke into my house and killed my mom.'" One of the home's glass doors had been broken and one room ransacked, say police, who are hoping neighbors' surveillance tapes might help. Dive teams were also searching a lake behind the home, reports CBS Local. (Another big murder case this week involves "altruistic filicide.")
