A man who detectives say shot and killed his adult son inside the family’s Palmetto Bay house was released from custody on Thursday, and no charges have been filed, according to the Miami-Dade Sheriff’s Office.

David Donald McPeck, 75, shot his son, David Dylan McPeck, 47, around 4:50 p.m. Wednesday at their home at Southwest 168th Street and 92nd Avenue during what the sheriff’s office describes as a domestic dispute.

The elder McPeck met deputies outside of the house when they responded to a 911 call about the shooting and was taken into custody, said Detective Argemis Colome, a sheriff’s office spokesman.

Miami-Dade Fire Rescue paramedics determined the son was dead from a gunshot wound when they arrived, Colome said.

A woman who says she is the younger McPeck’s sister told Miami Herald news partner CBS News Miami that her brother had a history of mental illness and attacked his father before getting shot.

“This is horrible for everybody. We’ve seen this coming for years. We have made plenty of phone calls, tried to get help from organizations for years, nothing has helped,” the woman, who did not want to be named, told the station. “Nothing has worked. I’m sorry that it has come to this. I don’t know what else to say. This is so tragic that it ended this way. I can’t even begin to tell you what this is doing to my family.”

Colome said it’s not clear if anyone else was in the house when the shooting happened, but a woman was outside the home when deputies arrived.

Colome told reporters at the scene on Wednesday that deputies had been called to the home several times in the past to deal with someone experiencing mental-health issues.

“The Miami-Dade Sheriff’s Office responds to a lot of mental-health calls. Something that I always suggest when I respond to these types of calls is, there’s always help. Please, there’s lots of hotlines, there’s a lot of numbers. You can call us. Because, at the end of the day, getting help can mitigate situations like this,” Colome said.

Colome said the sheriff’s office investigation into the shooting continues.
