Immediately, Jiang An asked, "Senior sister, did you participate in the entire scene investigation at that time?"
Zhang Yean nodded.
"Yes."
"I remember following Mr. Wu and two other senior brothers from the office to examine the scene."
"Did you measure the relevant data from the scene?"
Zhang Yean recalled for a moment.
"We should have measured it."
"At the time, I recorded the data. There should be relevant records in this dossier."
Then, Zhang Yean walked over, picked up the dossier on the table, turned back over a dozen pages, and found the scene investigation transcript.
"Look, all the data is on this paper."
Jiang An took the dossier and looked at it carefully.
He found that the measurement value of the body distance from the wall was 0.5 meters.
For a moment, Jiang An's heart raced at seeing this number.
For a body that falls from a height, if it is a jump, there must be an initial velocity.
