WICHITA, Kan. (AP) — Police are investigating the weekend deaths of four people in three Wichita neighborhoods as homicides.

Police said a woman returning home late Saturday found the bodies of her 62-year-old mother, Houng Pham, and her 23-year-old brother, Cody Ha. Police are asking the public for information in the case.

Sunday morning, 25-year-old Bryena Mcquitty was found dead at her home. Her 33-year-old boyfriend was booked into the Sedgwick County Jail on suspicion of second-degree murder.

Also Sunday, police found a 26-year-old Pizza Hut delivery driver dead in the trunk of his car. The victim, Hasan Rahman, had been shot.

Wichita police said Rahman didn't return to work after delivering two orders Saturday night. Police said the people who received his last deliveries aren't believed to be connected to his death.
