WORCESTER, N.Y. – Another teen has been charged in the death of Kenneth Robinson, who was allegedly shot and killed when his son and five others broke into his home and attempted to rob him.

Tatyana Febo, 17, of Downsville, N.Y., is the latest to be charged with first-degree burglary in relation to the incident.

"We could have charged her the very first night. They just didn't at that point in time because she was cooperating, she gave a full statement. It was later decided that she should be charged," said Otsego County District Attorney John Muehl.

The only adult charged in this case, 32-year-old Nicolas Meridy, claims that Robinson’s son, Dylan, shot his father in the head during the burglary. Muehl says it is unclear how Meridy knows the teens, who are all students at Oneonta High School.

"We still don't know, to tell you the truth -- I don't know what this 32-year-old is doing associating with 15-, 16- and 17-year-olds," said Muehl.

While the investigation is ongoing, Muehl says its too early to determine if any more arrests will be made in this case.

"I can't say yes and I can't say no right now. I don't see any, but it wouldn't surprise me if something comes up. This investigation -- things just keep popping up on us. We're dealing with new things every day," said Muehl.

Muehl is looking to prosecute three of the teens involved as adults, including 15-year-old Dylan Robinson, Anias Soto, 15, and Alexander Borgreen, 16. All three teens, and Meridy, face charges of second-degree murder and first-degree burglary.

Febo and 16-year-old Alexis Lotterman are charged with burglary and will not be charged with murder.

Meridy appeared in town court on Oct. 17, and reached out to NEWSChannel 2 after his hearing, stating he believes he was wrongly portrayed as a culprit in this case.

His letter reads:

To Whom It May Concern,

I send this missive to address my displeasure, of and for your top story concerning Nicolas Meridy for the crime of murder 2. You have portrayed me as culprit, thief and murder [sic], all misinformed with your information you have obtained thus far. If you would like the true story come to Otsego Count [sic] Jail and I will give you the real true story. I’m available to meet any time in the near future.

Sincerely,

Nicolas Murphy Meridy

Muehl says he is aware of the letter, and believes Meridy has been accurately represented.

"I'm familiar with the contents of the letter. I don't really have any comment on it. He's been portrayed for what he is. Simple as that," he said.

The judge at Meridy’s hearing found there was sufficient evidence to turn the case over to an Otsego County Grand Jury for their consideration and possible indictment. Muehl has 45 days to present the case to a grand jury.
