Scroll down for video . Amy Gellert was killed by an intruder at her parents ' house in Cocoa Beach , Florida , on March 20 , 1994 . As the 21st anniversary of her killing approaches , the Brevard County Sheriff 's Office is still looking for leads . Amy 's stepfather Robert Lehton ( left ) was stabbed once in the head and her mother , Charlotte , 'Bunny ' Lehton ( right ) , was stabbed seven times in the neck by the intruder . Amy had arrived at the house after attending church services . Before she stumbled upon the masked assailant , he had forced her parents to lay on the floor and taken money and credit cards from Bunny 's wallet , CBS reported . The man was behaving calmly until he saw the lights from Amy 's car and began stabbing her parents . After he was stabbed , Bob ran outside and the intruder followed him . Police say Amy was the 'catalyst ' for the 1994 killing . The killer arrived at Amy 's car and began stabbing her . She fled the vehicle , but only made it as far as a nearby parking lot before collapsing . Amy 's parents survived their wounds , but Amy did not . She had two older brothers , Mark and Ryan . Police have never arrested any suspects in connection with the murder and do not have a concrete motive for the deadly attack . Major Tod Goodyear was one of the investigators called to the crime scene in 1994 . He said : ' I have a hard time thinking this is a random act . 'The consensus tends to be that Amy 's the catalyst . 'There 's something there with Amy that probably caused this to happen . ' The unsolved cold case was featured on an episode of 48 Hours that aired on Saturday . During the episode , images of the weapons were aired and potential suspects were identified . Based on a magazine police found at the scene , they were able to determine the suspect had a prop gun . The dagger was never found . Although it seemed real during the attack , the intruder was actually armed with a prop gun ( pictured ) The dagger the intruder used to stab Amy , Bunny and Bob was never recovered by the police ( sketch shown ) Three suspects - Jeffrey Anderson , Hugh Poppell and Dominic Kanuika - were identified during the show . Anderson was involved in a police chase the day after Amy was killed and is currently in prison . However , police could never connect him to the murder . Poppell had a romantic relationship with Amy and police received a tip he may have been involved in the murder after he died in a hit-and-run accident in 2013 . Kanuika became a suspect after someone reportedly overheard his high school girlfriend saying he was 'possibly involved with that homicide ' . Even though he had a shaky alibi and failed a polygraph , police could never get enough evidence to suggest Kanuika was at the house . Three suspects - Jeffrey Anderson ( left ) , Hugh Poppell ( center ) and Dominic Kanuika ( right ) - were identified . Major Tod Goodyear ( left ) and the rest of his cold case team are still hoping to catch Amy 's killer 21 years later . Show producers and the Lehtons are hoping the episode will turn up some new leads for police . During the broadcast , staff members from the program monitored Facebook , Twitter and other social media outlets for tips , according to Florida Today . Show correspondent Erin Moriarty said : 'It 's not only unsolved but it 's really difficult to - even to this day after speaking with all the detectives who worked on this case - determine the motive . 'And that really is the reason why they have not been able to completely tie up all the strings and arrest someone . 'One person 's life was taken but so many other lives along the way were destroyed . ' During the broadcast , 48 hours staffers monitored Facebook , Twitter and other social media outlets for tips . Bob and Bunny , who still live in Cocoa Beach , hope that an arrest will help bring them 'closure ' . Bunny said : 'Our sole purpose is to give people an opportunity to give us information that will lead to the capture of the person who did this . 'This is not vengeance . 'He just needs to be off the streets for doing something so terrible . ' The sheriff 's office worked in tandem with 48 Hours on the episode . According to the department 's Facebook page : 'The CBS 48 Hours crew has followed the investigation for several months and has offered to help the investigation by seeking the help of the community . ' Anyone with information regarding the investigation should call the Brevard County Sheriff ’ s Office Major Crimes Unit at 321-633-8413 or email at MajorCrimes @ bcso.us .
