A Fort Worth man who kept changing his story when questioned by investigators about his wife’s death has been convicted of murder and sentenced to 35 years in prison on Friday.
Hermann F. Gninia, who turned 43 on Thursday, initially told an officer who responded to a medical call to his home in the 7200 block of Specklebelly Lane in east Fort Worth on Jan. 10, 2017 that his wife, Diossy Ndiaye, had fallen and hit her head on the side of the bed during an argument.
After giving her medicine, he left to borrow a neighbor’s phone, then returned to find her foaming at the mouth, he told investigators, according to an arrest warrant affidavit obtained by the Star-Telegram in spring of 2017.

Ndiaye was transported to Arlington Memorial Hospital, where she was pronounced dead.
However, in an interview with a homicide detective, Gninia said that his wife had fainted while he wasn’t in the room.
Later in the same interview, Gninia admitted to pushing Ndiaye during an argument.
Police found signs of a struggle in a bathroom, and in a later interview with detectives, Gninia admitted to pushing his wife a few times and squeezing her neck with his hands for about 10 seconds.
He told them he was angry with her because she wouldn’t stop talking, but that he felt bad and that what he’d done was wrong, according to the affidavit.
A detective said the couple was arguing after she accused him of infidelity, and that at least one child was present in the home when the incident happened.
Gninia admitted that he didn’t call for help for 20 minutes after strangling Ndiaye.
Gninia’s defense attorney filed an appeal of the ruling on Friday, court records show.
