According to an arrest warrant affidavit, obtained by KDFW and KXAS, Dallas Fire-Rescue responded to a fire at a mobile home park in Northwest Dallas early Saturday morning.

Authorities said that Lopez started the fire after one of the homeowners, whom she allegedly was in a relationship with and identified as Gary Fischer, refused her entry into his mobile home. Per KDFW, Lopez admitted to a neighbor that she started the fire after Fischer would not let her come inside his home to use the restroom, and she got upset. She also reportedly confessed this to police.

Per the affidavit, Lopez knocked on Fischer's door while he was sleeping. Fisher then allegedly told Lopez to leave, before he then shut the door on her and went back to sleep.

"There she was standing," Fischer told KXAS. "I said, 'Try later,' and I closed the door and locked it."

According to Fischer, five minutes later, he heard a loud noise, before he then saw the blaze outside his home.
