PORTLAND, Texas (NBC News Channel) -- The Portland, Texas Police Department and Texas Rangers have released a new sketch of the man they're looking for in connection with the shooting of Kristene Chapa and murder of Mollie Olgin.
The man in the sketch is described as a white man in his 20's, around 140 pounds, 5' 8" tall, with brown hair and a scruffy beard.
With the help of this new sketch, Mario Olgin hopes someone will come forward and turn in the man who took his daughter away.
"The loving girl that she was, she didn't deserve this," said Olgin. "Kristene's the same way. She didn't deserve this either."
Olgin says that his family is still trying to cope with the loss of their loved one, but there is one thought that still haunts him.
"When I think about her last 15, 20, 30 minutes on earth," he said, "how scared both girls had to be whenever they were approached by this monster."
This thought is what keeps him from not giving up on finding his daughter's murder.
He says he has one simple message for anyone who may know this man.
"It's been almost three weeks now and the longer it carries on the harder it's gonna be," he said. "So if somebody knows something, just come forward."
