(CNN) A Texas man has been charged with the murder of a woman he'd proposed to just days earlier, her family says.

Kendrick Marquette Akins, 39, made Dominic Jefferson his fiancée on New Year's Eve after three months of dating, her family told CNN affiliate KTRK

Just days later, on Saturday, he allegedly shot a woman he was dating after an argument, the Houston Police Department said in a statement. Her family told the affiliate that Jefferson was the victim.

Officers responded to a shooting call at an apartment complex in Houston, and a witness believed the victim's boyfriend fled the scene, police said.

A witness told the officers Akins appeared to leave but then came back and confronted a "concerned citizen" who was trying to help the woman, the department said. Akins fired a shot at the direction of the citizen and then fled, a witness told officers.
