Sams, the maker of the $1.99 Love Seat recliner and other recliners from Ikea, said it would offer a $1 million reward for information leading to the capture of the gunman, and pledged to give back any money it collects.
Sams, which said it is owned by Ikea , said it was working with law enforcement authorities and that it has begun a $100,000 reward for any information that leads to the identification of the shooter or leads to his capture.
The company, which makes furniture and kitchen accessories for the home, said in a statement it is working with investigators to gather more information.
Samps said it will donate the funds to the U.S. Marshals Service, which will use the money to hire more than 100 new police officers to bolster its efforts to locate and capture the gunman.
The gunman, who is described as an adult male in his early 20s, was last seen entering a home in the neighborhood in South Philadelphia early Friday, the police department said.
The motive behind the attack remains unclear.
Police in the city said the man may have planned to target a large group of people but did not say what he may have wanted.
