PHILADELPHIA (AP) — The hunt for two Philadelphia carjackers who rammed a stolen SUV into a family, killing three children, entered its third day Sunday as officials offered a $110,000 reward for information leading to their capture.

Investigators said they are working hard to apprehend the suspects, who fled on foot after crashing the vehicle Friday at an intersection in North Philadelphia where Keisha Williams, 34, and her three children, aged 7 to 15, were selling fruit for a church fundraiser.

Late Sunday, Homicide Capt. James Clark said two men were being interviewed by detectives concerning the crash, The Philadelphia Inquirer (http://bit.ly/1ux8gcs) reported. Clark declined to identify the men.

Williams remained hospitalized, along with a 65-year-old woman who was helping the family at the fruit stand and the 45-year-old woman who had been carjacked at gunpoint.

Williams' 10-year-old son died at the scene. His older sister and younger brother were pronounced dead at hospitals.

"There are no words to describe how I feel right now, but we do need to find these two guys," said police Commissioner Charles Ramsey.

Investigators said the two assailants forced the SUV's owner, a real-estate agent, into the back seat about a mile from where the crash occurred. Investigators believe the carjackers may have blown a tire turning a corner at high speed causing the SUV to crash into a stand of trees.

The reward money was posted by the city and the Fraternal Order of Police.
