When Maldonado went through the back door, he was confronted by another man.
The two got into a heated argument that was loud enough to compel neighbors to call 911.
The man reportedly shot Maldonado during the confrontation.
The district attorney's office has decided not to file any charges. Prosecutors determined there was not enough criminal evidence.
Maldonado, 49, was the owner of Dean Maldonado Bail Bonds.
