that is sad, anyways i have had 2 res die and almost a third. one had started making a kind of cough sound for about a week then started this mouth opening and yawning for a couple of days then to my horror i looked down at the turtle and it was like choking then went limp and dead and was really cold so i took him/her out and held in hands to warm up 2 hours later it was alive so i warmed the water to 85 and rushed it to the vet in morning got 2 shots 1 for each front leg amikacin, and baytril,amikacin is time released anti biotic lasts 5 days max. then u need to give it .01 milliters of baytril either injected
into front legs above knee joint towards the turtles face

.....or i suggest inject a worm or a guppy and he/she should gulp it down. water must be 85 when sick but it sounds like ur turtle drowned and it should have had oxegen immediatly first then the shots. sorry for ur loss i have lost 2 res due to refusal to eat
