CHARLOTTE, N.C. -- The man charged with killing his twin daughters has been moved to a prison's mental health facility in Raleigh.

It wasn't attorneys on either side, but rather mental health workers inside the Mecklenburg County Jail who pushed to have David Crespi moved to central prison's mental health unit.

On Tuesday afternoon, a judge signed a safekeeping order. The order said Crespi is "suicidal and under suicide precautions" at the jail in Raleigh.

Authorities said Crespi is in a windowed room where he is observed constantly either by medical or jail employees.

The state prison system officials said Crespi will first be evaluated by a psychiatrist. Then, depending on his mental condition, he will remain under some kind of suicide watch.

Officials said Crespi will be placed in a single room monitored by cameras and be given clothing that can't be ripped or torn or used to hurt himself.

Neither the mental health workers nor the jail in Charlotte will comment on what triggered the decision to ask that Crespi be moved.

Crespi's attorney, Jean Lawson, said she doesn't object to the transfer.

Every time a person is arrested and put in jail in Mecklenburg County, the jail's medical staff evaluates their physical and mental condition. They evaluate whether there are any signs that suggest the risk of suicide, assault or abnormal behavior or if the inmate experienced feelings of hopelessness in the past or feels like there is no way out.
