At the beginning of class, Matt realized that he had forgotten the essay that he had wrote at 4 a.m., so he smeared blood-like streaks of red pen at the corners of his mouth and told his instructor, Professor Borglum, that muggers had beaten him up before stealing his backpack.

The second verb, had wrote, is incorrect. This verb requires the past participle written because of the auxiliary verb had.
