A Baker man described as an "enforcer" was sentenced this week to nearly 22 years in federal prison in a massive drug case that has netted 34 convictions and involves allegations of murder plots, using children to transport narcotics, storing cocaine at a Baton Rouge day care center, and threats of using a hatchet to cut off the fingers of a man who owed money.

Court-authorized wiretaps captured Myron Chevelle Hart, 39, and a fellow conspirator planning to rob and kill someone because the person had talked negatively about them, U.S. Attorney Walt Green said Thursday in a news release.

In another telephone conversation, Hart bragged to a different co-conspirator that he should watch the news the next morning because the killing would be a story, Green stated, adding that in addition to distributing cocaine and crack cocaine, Hart's role in the violent drug trafficking organization was that of an enforcer.

Law enforcement intervened and prevented the murder plan from being carried out, he said.

Hart pleaded guilty in November to conspiring to obtain and distribute cocaine and crack cocaine for profit in and around Baton Rouge, and was sentenced Wednesday to 262 months behind bars by U.S. District Judge Shelly Dick.

The judge also handed Hart a concurrent four-year term for violating his federal supervised release stemming from his 2007 drug and firearm convictions.

Hart was among 39 people indicted by a Baton Rouge federal grand jury in 2015 in an operation dubbed "Operation Third World." Some of the drugs traveled through Houston but likely had connections to Latin America, federal drug authorities have said.

The indictment alleged cocaine was being stored at Emmanuel Child Development and Learning Center on Swan Avenue in Baton Rouge. It closed the day before Green announced in July 2015 the arrests of 38 people allegedly associated with the drug ring. A 39th person, D'Andre Tavis Smith, also was named in the indictment but was shot to death the same day it was issued.

Among those arrested and indicted were Kimberly Ann London, the day care center director, and her husband, Kelly D. Williams. Both have pleaded guilty and are awaiting sentencing.

London admitted allowing Williams to use the day care center to store cocaine and proceeds from drug sales. She also admitted failing to tell authorities about the crimes. Williams pleaded guilty to various charges, including distribution of crack cocaine and oxycodone, conspiracy and possession of a firearm by a convicted felon.
