UPDATE: Steve Stephens killed himself after being spotted by Pennsylvania State Police in Erie County Tuesday morning.

Philadelphia police put eight elementary schools and a high school on lockdown midday Monday as they looked into reports of the Cleveland Facebook shooting suspect being in the Fairmount Park area.

Police stressed in a short news release that as of 1:30 p.m. there was "no indication that that subject is in the (Belmont) Plateau area." Police had received multiple 911 calls around 12:30 p.m. indicating that a person looking like the suspect, Steve Stephens, could be in the large urban park.

Stephens posted video of himself shooting and killing Robert Godwin Sr., 74, in Cleveland on Facebook Live Sunday, authorities said. Since then, the FBI warned that Stephens could have fled from Ohio. Investigators also said his cellphone signal was last detected Sunday afternoon in Erie, Pennsylvania.

"He could be nearby. He could be far away or anywhere in between," FBI agent Stephen Anthony said on Day 2 of the manhunt for Stephens, a 37-year-old job counselor for teens and young adults.

Philadelphia police vehicles could be seen patrolling Fairmount Park and helicopters could be seen overhead. Officers from five separate police precincts responded, police said.

Microsoft's School of the Future on Parkside Avenue was among the schools locked down. The lockdowns were lifted shortly before 3 p.m.

Despite the search, families continued to enjoy the warm weather in the park, strollers visible from nearby Montgomery Drive. At this point police don't believe Stephens is in Philadelphia.
