The police gave serious consideration to Shi Lan's strategy because in the police station, Ding Hong confessed to many shocking things.
First, she admitted that she had poisoned Shi Mother, explaining all the details very clearly.
Second, she described why she had been persecuted and the process through which it occurred.
Lastly, she revealed that she had overheard that last year's car accident involving Miss Shi was a plot concocted by the Shi brothers and Si Junlan.
Her own crimes were irrefutable, and with Shi Lan keeping Huo Zhao guarding that suspicious "fixer", it was a piece of cake for the police to apprehend them.
However, although there were eyewitnesses and physical evidence confirming that she had been drugged and framed into the mental institution, there was no direct evidence linking the Shi brothers and Si Junlan to these acts—and the investigation by the police was still necessary, not to mention the car accident from a year ago.
