LAWRENCE, Mass. (AP) — Hundreds of mourners have come out to remember the Massachusetts teen killed in last week's natural gas explosions north of Boston.

Some 300 people came out to St. Mary the Assumption Church in Lawrence to remember 18-year-old Leonel Rondon, the Eagle-Tribune reported.

Family members and friends cried and hugged each other tightly as they wore white shirts bearing the words "RIP Leonel" and "It's Leo's world, we're just living in it," the Boston Globe reported.

Rev. John Dello Russo remembered Rondon, who was a local musician who went by the name DJ Blaze, as a teen with a bright future.

Through the devastation and tragedy that rocked Lawrence, Andover and North Andover, he said, the best of humanity emerged.

"Last Thursday afternoon, all hell broke loose in our city," Dello Russo said. "But in the midst of it, people helped one another out. In ourselves we found power, compassion, love."

In her eulogy, Leomary Colon recalled how her cousin had tried to cheer her up at a homecoming dance. He told her, "You got to live it until it's gone."

She said she'd miss his advice and support. "He took care of everyone," Colon said. "You knew you were in good hands with him."

The high school junior died Sept. 13 after the chimney of an exploding house crashed into his car and crushed him. Rondon had just received his driver's license hours earlier.

About 25 other people were injured in the three Merrimack Valley communities. Dozens of homes were damaged or destroyed and thousands of residents were forced to evacuate.

Nearly 9,000 homes and businesses may be without gas for weeks as investigators continue to probe what set off the explosions.

The National Transportation Safety Board, which is heading the inquiry, has said investigators are partly focused on pressure sensors that were connected to a Columbia Gas pipeline being taken out of service shortly before the blasts.

The gas company, meanwhile, said Wednesday it would withdraw a $33 million rate increase that had been scheduled to take effect in November for its more than 320,000 gas customers in Massachusetts.

The rate hike had been approved prior to the explosions, but Columbia Gas of Massachusetts president Steve Bryant said in a statement the company is instead focused on recovery efforts and "re-establishing trust" in the company.
