So, here's the case:
Mr. Jam was killed on Friday at 5:30 p.m, in the garden. Meanwhile, all the students had gone home. There're just few people left: (according to the witness)
- Mrs. Annie, who's feeding her fish in the biologic room.
- Mr. Thomason, who's preparing the lessons for the next day.
- Ms. Jennifer, the gardener, who's going home soon. (witness)
- Mr. Brown, the Math teacher, staying with Mrs. Annie.
Who's the murderer?
