Horrifically, the couple’s 5-year-old twins were present in the home when it all unfolded. The twins are a boy and a girl, and they were not physically harmed.

“No, daddy. No. I don’t want anyone to die,” one of the twins can be heard saying to their father as he accused his wife of cheating on him. “I don’t want anybody to die.”

“Please don’t shoot …” a child is also heard on the audio, according to Florida Today. You can hear Stillwell tell the children he loved them in the 911 audio. “Don’t shoot mommy,” a child implores at one point.

“Come help me please!” a woman screams.

2. An Affidavit Accuses Stillwell of Unleashing Expletives as He Stormed Over to the In Laws’ House With a Gun

The Melbourne Police Department confirmed that there were three victims, writing, “On 1/01/19, The Melbourne Police Department received calls of a disturbance at 3243 Woodsmill Drive.Officers arrived and located three victims. They received medical attention and were transported to a local hospital for further evaluation and are currently listed in stable condition. The suspect surrendered to officers and was turned over to the Brevard County Sheriff’s Office.”

According to the arrest affidavit, Stillwell is accused of showing up armed with a black Sig P226 9mm semi-automatic pistol. It was an “unannounced, unplanned visit.” The first victim asked the defendant to leave, but he “entered the fenced in backyard without permission,” the affidavit alleges.

Stillwell is accused of saying, “f*ck you, you son-of-a-b*tch” and “immediately fired,” the affidavit says. The victim, his father-in-law, ran to a neighbor’s house for safety. At that time, the second victim, the mother-in-law, “exited the residence and was shot two times by the defendant” in the yard. She was struck in the left elbow and abdomen, says the affidavit.

Stillwell is accused of unleashing a string of expletives, stating, “f*cking b*tches and wh*res, take that.”

Inside, he encountered his estranged wife calling 911. At one point the defendant said he should be shot in the head. He stated “f*ck you, f*cking wh*re” before firing, the affidavit contends.

In another release, police provided additional albeit more generic details: “The Melbourne Police Department received calls of a disturbance at 3243 Woodsmill Drive. Further information received indicated someone involved was shooting a firearm. Updates indicated there were victims. Officers arrived and located three victims. They received medical attention and were transported to a local hospital for further evaluation. As of now there are no fatalities. A perimeter was established on the home and the suspect surrendered to officers. The involved parties appear to share domestic relations and have all been accounted for. At this time there is no danger to the general public. Melbourne Police Department is actively investigating and will provide updates as soon as we are able.”
