> - The officer in the training exercise that killed Officer Tipping has the same name as the officer in Tipping’s report, but they are not sure if it is the same person.

It appears you did not finish reading TFA. There was an investigation that confirmed the same officer was at the training:

"Gage could not confirm that the officer accused of rape was the officer directly engaged in the training exercise with Tipping. But he said 'our investigation indicates that yes, it was.' "

And frankly, if you don't think it's suspicious that an officer who investigated four LAPD officers raping a woman later getting killed in a freak bicycle training accident isn't suspicious, you may need to reset your baseline for what is "speculation and innuendo." What happened here was extremely suspicious. Even before considering that one of those officers charged was at the training.

(One may even wonder why a police officer accused of rape was not only still on duty, but even training other officers.)
