SUWANEE, Ga. (AP) — Police in Suwanee say a man accused of stabbing his estranged wife to death during a custody swap in a Walmart parking lot has been charged with murder.

Capt. Cass Mooney, a Suwanee police spokesman, says 28-year-old Phillip Chad Dunn, who police say stabbed himself when he attacked his 27-year-old wife, Shelley Dyan Dunn, on Sunday, has been released from a hospital. He was taken to the Gwinnett County Jail.

Mooney says Dunn is charged with malice murder and felony murder.

The couple’s daughters, ages 6 and 8, were present when the stabbings took place. Mooney says it’s not clear whether they witnessed the attack.

The district attorney’s office and Superior Court were closed on Monday, and it could not be determined if a court hearing had been set.
