Police returned to the streets of Anna Palmer's neighborhood Friday, passing out fliers in a desperate appeal to solve the nearly month-old murder of the child.

Anna, 10, was found stabbed in the neck on the front porch of her home at 1633 S. 300 East on Sept. 10.Despite an intensive neighborhood canvass seeking witnesses to the attack, which occurred in broad daylight, police have come up with no one who saw anything that has produced a credible suspect.

The little girl was attacked after she left a neighborhood playmate's house at 7 p.m.

Several children saw her running home and said she appeared happy and unafraid.

About 30 minutes later, her mother found her bloodied daughter crumpled on the front porch of their home. Police say they don't believe she was sexually assaulted.

Anna died on the way to the hospital.

Detectives have interviewed family members, a battery of neighbors and have cross-referenced reports of lewd behavior exhibited by a male asking for directions in that neighborhood on the day of the attack.

A mental patient at the University of Utah Hospital has confessed to the murder and police are hoping to talk to him, Sgt. Kyle Jones said.

However, police are not putting much credibility in the confession, since the man also claimed responsibility for the shootings at the U.S. Capitol that were committed by another man who remains in custody.

Early last month, police came forward with a $5,000 reward to be given to anyone with information that leads to the identification and arrest of a suspect in Anna's slaying.

Jones said the department has developed a system that will allow tipsters to remain anonymous by assigning them a sequence number that will be the only identifying factor about the tip.

"We are hopeful the reward will be a motivator. Perhaps someone will come forward who has been reluctant in the past."

If anyone has information, they can call police dispatch at 799-3000, or the homicide division at 799-3730.
