text: The father one of one three children who were tragically killed in Palm Bay, Florida, in March has spoken out about the kids he cared for and loved. Seven-year-old Lacey McCarty, six-year-old Phillip McCarty and five-month-old Christopher Swist died allegedly at the hands of their mother, Jessica McCarty, in a botched murder-suicide. Christopher Swist - father of the five-month-old and the man who was dating Jessica McCarty just before the alleged killings - had nicknames for all of the children and coached the two oldest in little league baseball. Scroll down for video . Jessica McCarty, pictured with her partner Chris Swist, daughter Lacey McCarty (right) and sons Philip McCarty (center) and Christopher Swist (in her arms), called the police on herself . McCarty was arrested on March 20 and faces three counts of first-degree murder for the incident. Investigators say she left a note behind at the scene saying she was 'sorry for what she had to do' Just 24 hours before their death, he took pictures of the two oldest children at their latest game, and both looked happy as ever, Swist said. 'The kids loved everything about Little League,' Swist told People. 'The past two years, we watched the Little League World Series on ESPN. Our families were always at all the games.' Their love of the sport was so strong that  Palm Bay City Council has renamed a little league field in their town 'Angels' Field' in memory of the children. Swist said that he had a great bond with the children, calling Lacey 'Chick', Christopher 'Toe Toe' and Phillip 'Smash'. As he comes to terms with the tragic deaths of the three kids he loved so much, Swist has created a non-profit organization titled 3 Angels Ball For All, in hopes of helping disadvantaged youth play organizational sports. Jessica McCarty still faces three counts of first-degree murder for the incidents that occurred on March 20. McCarty's partner, Christopher Swist, who she was reportedly on a break with at the time of the alleged murders, coached her two oldest children in little league baseball . Swist, who was only the father of the youngest slain child, said he had a close bond with all three children and gave them all nicknames to go by . Swist called seven-year-old Lacey (right picture, left) 'Chick', five-month-old Christopher (left) 'Toe Toe' and six-year-old Phillip 'Smash' (right). Each nickname supposedly had a story behind it . McCarty was arrested after she called 911 and told police she'd killed her children. Lacey and Philip were found unresponsive in the same room at the home and were pronounced dead that night. The mother strangled the infant and drowned and strangled the daughter, Palm Bay Police Chief Mark Renkens said, according to Florida Today. Police say none of the three children were shot or stabbed, but lacerations were found. Christopher Swist had been on life support at Florida Hospital for Children  but lost his fight for life in the days following the attack. 'Our hearts go out to the friends and family who have lost children in such a horrific manner. The fathers of these helpless, innocent children struggling is simply gut wrenching,' said acting Palm Bay Police Chief Mark Renkens said after the incident. According to Renkens, there had recently been a break in the relationship between McCarty and  Swist. Lacey and Phillip where pronounced dead shortly after they were found unresponsive. Christopher held on for a couple days before dying at the hospital . McCarty was arrested after calling 911 on herself and telling the police she had killed her three children . When Swist arrived on scene - after McCarty had sent him photos of blood throughout the house - and found the children unresponsive. He then called the police . Investigators said McCarty sent photos to Swist of blood throughout the house. Swist arrived first at the scene and found his son unresponsive on his bed, police said. Police said they found a journal in the driveway of the home that was addressed 'To my family,' which indicated that McCarty was sorry for what she 'had to do.' There was also another page addressed to Christopher's father, asking him to keep her son's name alive, police said. In a mugshot provided by the local jail, the troubled mother appeared in a suicide-prevention vest with bandages covering her recently-slashed wrists - her mouth agape. The motive for the tragic attempted murder-suicide has not been revealed. However, McCarty did have a troubled history and in 2009 was investigated by the DCF for possible child neglect. The agency recommended McCarty to mental health counseling after that investigation, according to public records. Phillip McCarty (left) was the father of the Phillip and Lacey, the two older children McCarty is believed to have killed on March 20 . McCarty and Swist had one child together - five-month-old Christopher. Police said they were on a break at the time of the incident . She has also been arrested on charges of forgery, shoplifting, and prescription drug abuse. Police were first called to the family's residence just before 6pm, when McCarty called 911 to say her three children were dead and that she had cut her wrists. Swist also called police when he came home. Swist now has the comfort of his city's support in mourning and remembering the three children he loved. 'All I have left is the memories that my children blessed me with,' Swist told People. 'Those moments will forever be ours together. Those children touched so many lives in the community; naming the field after them is a great way to help keep those memories alive.' And he knows he has to push on and have the strength to hold his memories close. 'I don’t think you ever heal from this,' Swist told Space Coast Daily. He added: 'The best we can do is survive. The way we survive is we all stand together as one family. 'As far as you guys even thinking about naming the field, that really means a lot to us. We just can’t say enough. We miss our kids. We miss our kids.' Though Phillip and Lacey were not Swist's biological children, he cared for and loved them both. He claims that the children 'touched so many lives in the community' of Palm Bay .
