BATON ROUGE — A passenger in a car that last summer struck a man and severed an arm has been arrested and accused of improperly involving herself in the investigation and taking gruesome pictures of the victim and sending them to the driver. 

Katyra Selders, 25, is accused of being a principle to hit-and-run driving, obstruction of justice, criminal conspiracy and failure to seek assistance.

The crash occurred along Siegen Lane near Interstate 10 last June. Another passenger, Marcus DePriest McNair Jr., 23, was arrested initially for multiple felony charges, and days later the man suspected of driving the vehicle was picked up. Kyron T. Fisher, 25, is accused of hit-and-run driving with a serious injury, obstruction of justice, criminal conspiracy and negligent injuring,

According to arrest documents, police quickly found the car involved and its driver told officers that he had left the scene of the crash after a woman on the scene had told him to leave, that witnesses would call authorities, and that she would call if investigators wanted to speak to them.

That woman turned out to be Selders, according to state troopers. Arrest documents for Selders say she sent several gruesome images of the pedestrian victim to the driver of the vehicle, including pictures of the man's severed arm, with one message reading "I know y'all feel bad."

Selders allegedly made no attempt to contact authorities after sending the driver away and then did not tell police that she had been in contact with him.

Selders was arrested Friday and posted a $6,000 bond Sunday and was released. 

Fisher had marijuana on him when he went to Troop A in May to surrender and was also accused of drug possession.

Fisher's first name has been spelled "Kyron" and "Kyrone" in State Police documents.
