Investigators on Thursday were learning more about the man who shot two co-workers inside an Ohio State University maintenance building before turning the gun on himself.

Some of the last messages left by Nathaniel Brown were released Thursday by the Franklin County Coroner's office, 10TV's Tino Ramos reported. 

The notes appear to reference a girlfriend named Donna and state, "Sorry I let you down," Ramos reported.

Another note left by Brown reads, "Everything I have, Donna J. Dunson can have."

University Police on Wednesday raided Brown's north side home, but sources told 10TV the search warrant may be sealed, meaning the details of what was taken from the home may never be released, Ramos reported.

The investigation is continuing, while plans were underway for a campus vigil Thursday night, Ramos reported.

Students, faculty and staff will gather for a candlelight vigil to remember Larry Wallington, who was shot and killed Tuesday, and to wish Henry Butler a speedy recovery.

Wallington, 48, and Butler, 60, were co-workers of Brown, Ramos reported.

The vigil will start at 5:15 p.m. under the south side stands of Ohio Stadium, Ramos reported.
