An endangered person advisory is still in effect for a 4-year-old girl who was last seen on Monday.
The Phelps County Sheriff's Office issued the advisory on Wednesday evening for Cassandra Robertson, who was last seen in the 11800 block of State Highway V near Rolla.
Cassandra is a white female, about 2 feet, 6 inches tall. She weighs around 40 pounds. She has brown hair, blue eyes and was last seen wearing a gray zippered shirt with a Hello Kitty logo.

Cassandra is believed to be with her mother, Nikie Robertson, 39, described as a white female, 5 feet, 6 inches tall with brown hair, green eyes and wearing a black shirt and blue jeans.
"We still haven't heard anything at all," Phelps County Sheriff Rick Lisenbe said Thursday afternoon. "Our focus is to find the child and make sure she gets what she needs. I think the most important thing for us is to find her and make sure she's all right."
According to Cassandra's father, the youngster has an eye infection that requires medication. It was also reported that the mother, Nikie Robertson, has a history of suicidal tendencies and substance abuse.
Lisenbe on Thursday afternoon said he was expecting the county prosecutor's office to get involved, but it was too early to determine whether or not charges would be issued.
Lisenbe said more information should be available soon.
"Right now, they're nowhere to be found," the sheriff said. "We haven't had any contact, but hopefully once this gets put out we will."
The mother and Cassandra may be en route in a silver 2006 Nissan Quest bearing Missouri license plates FG2D5J to Las Cruces, N.M., or Colorado.
Anyone seeing the missing person, suspect, associate or vehicle, or anyone having any information related to the endangered missing person should immediately dial 911 to contact the nearest law enforcement agency or call the Phelps County Sheriff's Department at 573-426-3860.
