LAUREL, Md. (AP) - Authorities say the northbound lanes of Interstate 95 have been closed in Laurel after a person fell or jumped from a highway overpass.

Prince George's County fire department spokesman Mark Brady says the person was killed after falling from the Brooklyn Bridge Road overpass north of Route 198. It happened around 3 p.m. and led to the shutdown of the northbound lanes.

Brady says the incident is being investigated as a possible suicide. No one else was injured.

LAUREL, Md. (WUSA9) -- Prince George's County Police are investigating the deaths of two people at an apartment complex in the 9600 block of Muirkirk Road in Laurel.

We are told somebody called the police worried about the welfare of the couple that lives in that apartment and their young adult daughter at approximately 8:22 a.m. Thursday. When the officer arrived, he found the couple dead -- a man and a woman in their 40s -- and a young woman, who neighbors say is a quadriplegic, in need of medical help. She was rushed to the hospital for an evaluation, say authorities. She is expected to be released soon.
