The details surrounding the mass shooting at a Central Florida nightclub on Saturday night are getting worse by the minute. There's a new report that says one grieving mother is recalling the last heartbreaking text messages she received from her son, who was killed during the terror attack.

According to the Associated Press, Mina Justice says her 30-year-old son Eddie was inside Pulse nightclub in Orlando when alleged shooter Omar Mateen killed 50 people and injured at least 50 more in what many are calling the bloodiest mass murder in U.S. history. Multiple reports also say that Mateen, who was born in the United States to Afghan parents, pledged his allegiance to ISIS before opening fire.

Justice says that her son texted her when the shooting began at approximately 2 a.m., asking her to alert local law enforcement and authorities as soon as possible. He said that he was hiding in a bathroom along with other club goers.

He texted his mother, "He's coming. He has us, and he's in here with us." Justice said that was the last conversation she had with her son.

Meanwhile, someone reported posted via  the night club's official Facebook accont "Everyone get out of Pulse and keep running."

Just before 6 a.m., the club posted an update: "As soon as we have any information, we will update everyone. Please keep everyone in your prayers as we work through this tragic event. Thank you for your thoughts and love."

Mateen was shot at the scene during a shootout with police.
