I-Team: What Happened to Calvin?
But Calvin’s twin sister, Dornett Mullings, thinks investigators got it wrong, and left too many questions unanswered. She’s done her own digging, hired independent experts to review evidence, and launched an online petition calling on the police department to re-open the case.
“I suspect foul play,” Mullings told the I-Team. “But the only way we can find out is for a thorough, methodical, meticulous investigation. We have not had that.”
The autopsy lists Calvin’s cause of death as an accidental drowning, complicated by diphenhydramine, the drug found in Benadryl. A toxicology screening found 7.22 milligrams per liter of diphenhydramine in Calvin’s blood, many times higher than ordinary use.
Detectives determined Calvin must have “accidentally” ingested more than a dozen Benadryl pills, became disoriented, and then wandered into the canal behind his home and drowned.
At Mullings’ request, forensic pathologist Dr. Ronald K. Wright reviewed the autopsy and the police report.
As the former Medical Examiner for Broward and Miami Dade Counties, Dr. Wright estimates he has reviewed more than 12,000 cases, and based on his experience, he thinks this medical examiner got it wrong in Calvin’s case.
“The one thing this is not, is an accident,” Dr. Wright told the I-Team.
He believes it’s unlikely anyone could “accidentally” take as much Benadryl as Calvin had in his system – meaning he either intentionally took his own life, or someone else did.
And while Calvin’s body was found in the water, Dr. Wright tells the I-Team it’s possible – even likely – that he died before his body was dumped in the canal. That’s because a hallmark of drowning is the presence of liquid in a person’s sphenoid sinus, or the area behind the nose.
In Calvin’s case, the medical examiner reported in the autopsy: “There is no fluid in the sphenoid sinus.” And in the police report, summarizing the autopsy, it states: “There were no sure signs of drowning.”
Dr. Wright believes Calvin’s case should have been ruled differently: “It’s undetermined. That’s what I would have classified it as. This is a case where I don’t think anybody was that interested in looking into the questions.”
And there are many questions, when you take a deeper look at the evidence.
First: the source of the Benadryl. If police believe this is the medication that played an instrumental role in his death, why was there no mention of finding empty pill packets or receipts for Benadryl in the Berry home?
A second concern involves the recording of the 911 call made by Calvin’s wife. She told police that she was alone, but if you listen carefully, you can hear what may be whispers form someone else on the line. If it was someone else whispering, who was it? And why were they there? What were they saying?
Another puzzle: Calvin’s pacemaker transmitted data to a remote server, showing that his heart was shocked at 2:35 a.m. – a few hours after he went missing. That seems to indicate he was still alive at that time, and that his heart needed help to restore its normal rhythm. If he was alive, where was he, and why was his heart racing?
If Calvin really did wander into the canal behind his home after taking Benadryl inside, why do police reports state that blood hounds followed Calvin’s scent away from the canal, and down the street? An initial drone search of the water the night he went missing showed no signs of him in the water.
Calvin left his cell phone behind the night disappeared, but someone did use his phone. His call log shows an incoming call from an unidentified number at 2:54 a.m. The call was answered, and it lasted 54 seconds. Calvin’s wife told police she had “no knowledge” of the call, and “denied answering it,” according to the police report. Who was calling? Who answered it? And what was said?
Finally – and perhaps most alarming – are the concerning text messages two of Calvin’s adult children received after he was reported missing, before his body was found. An anonymous person sent messages saying, “I have Calvin He is sick.” The texts demanded a $7,000 ransom, and threatened to kill Calvin.
Port St. Lucie Police investigated these ransom texts and determined this was a “hoax” because the number appeared to originate from overseas. But how would someone overseas get the phone numbers for Calvin’s children? And could it have simply been someone local “spoofing” their number to disguise their origin? The police report doesn’t say.
“Nothing makes sense. Nothing is adding up,” Mullings said. “The dots are not connecting. And I’m asking questions. And I’m getting no answers.”
The I-Team reached out to the Port St. Lucie Police Department to ask questions about this case. A department spokesperson said there were “no detectives available.”
