Son gets call showing duct-taped dad before he’s killed in Baltimore, feds say

A Baltimore man lured a father from California to Maryland to discuss their marijuana business, then called the father’s son, showing him bound to a chair with duct tape covering his mouth before he was shot to death, federal prosecutors said.

Over the FaceTime call, Ziyon Thompson filmed Miguel Soto-Diaz from inside a Baltimore row home and demanded “200 pounds of marijuana and $50,000” from his son in exchange for his father’s “safe return” on May 8, 2022, according to prosecutors.

Soto-Diaz was tortured, and when his “kidnappers’ demands were not met, (he) was shot five times,” court documents say.

His body was found by Baltimore firefighters, who were called to the home as it burned in a fire, according to prosecutors. Investigators with the city’s fire department believe the blaze was “intentionally set,” court filings say.

Now, Thompson, 21, has been sentenced to 22 years and one month in prison over aiding and abetting the killing of Soto-Diaz, the U.S. Attorney’s Office for the District of Maryland said in a June 3 news release.

“Murder is widely accepted as the most egregious crime,” prosecutors wrote in a sentencing memo ahead of Thompson’s June 3 hearing. “Here, we have a family that lost a father, husband, and caregiver.”

Thompson previously pleaded guilty to use of a firearm resulting in death during and in relation to a drug trafficking crime, court records show.

Federal public defenders appointed to represent him, Katherine Tang Newberger and Sasha Garcon, didn’t immediately return McClatchy News’ request for comment June 4.

In court documents, his legal counsel argued Thompson wasn’t there when Soto-Diaz was killed and that he did not want him to die.

“Nonetheless, he knows he is morally and legally responsible for a death that deprived a loving wife of her husband and a child of his father, and he tears up when discussing Mr. Soto-Diaz, his wife and child,” his public defenders wrote in a sentencing memo.

The filing mentions Soto-Diaz’s wife was pregnant when he was held for ransom in Baltimore.

Others involved in his killing weren’t identified by prosecutors.

The month before Thompson was accused of luring Soto-Diaz to his death, he visited Soto-Diaz and his family at their California home in late April 2022, according to prosecutors.

Thompson stayed with Soto-Diaz to see “the family’s marijuana ‘farm,’” then “agreed to sell Soto-Diaz’s marijuana in Maryland,” court filings say.

In charging documents, a special agent with the Bureau of Alcohol, Tobacco, Firearms, and Explosives described Soto-Diaz as a “marijuana trafficker.”

Soto-Diaz’s son regularly communicated with Thompson for his father because Soto-Diaz didn’t speak English, according to prosecutors, who said his son would translate their texts and calls.

After Thompson’s California visit, he had an issue with “the quality” of Soto-Diaz’s marijuana and came up with a “ruse” to have the father visit Maryland, according to court documents.

Soto-Diaz went to Maryland while believing he and Thompson were going to discuss marijuana sales on May 8, 2022, when he was picked up by Thompson at a Baltimore hotel, prosecutors said.

Thompson took him to the Baltimore row home, where Soto-Diaz was tied to a chair, with duct tape covering his mouth and zip-ties binding his hands and ankles, according to prosecutors.

After Thompson demanded a ransom payment, he texted Soto-Diaz’s son, according to prosecutors, writing:

“Pap said send the bags and money so he can be ok and he said don’t call the police or he want (sic) be coming home.”

An autopsy revealed Soto-Diaz died from being shot in the Baltimore row home, not the fire that burned the residence afterward, according to prosecutors.

In seeking a 25-year sentence for Thompson, before he was handed a 22-year and one-month sentence, prosecutors wrote in the sentencing memo that Thompson agreed it was “reasonably foreseeable that Soto-Diaz would be killed during the extortion.”

Thompson’s sentence is to be followed by five years of supervised release, according to the U.S. Attorney’s Office.
