Police say a St. Louis police officer who was shot in the head while responding to a shooting remains in critical condition.
St. Louis Police Department spokeswoman Officer Michelle Woodling says a second officer who was shot in the leg was treated and released after the shooting around 6 p.m. Saturday in the South Grand neighborhood.
The gunman barricaded himself inside a home and police negotiated with him for nearly 12 hours before the 43-year-old was taken into custody Sunday morning.
Police have released no details about his arrest.
The gravely injured officer is 29 years old and has been on the force 3 1/2 years.
