The Houston Police Department said at about 10:35 a.m., a man's body was recovered from Brays Bayou in the 6800 block of Lawndale Street.
Investigators said a pedestrian on the Brays Bayou Greenway noticed a body near the opposite bank of the bayou and flagged down an off-duty HPD officer, who reported the incident.
The HPD Dive Team responded to the scene and recovered the man's body from the water.
Shortly after, at about 11:10 a.m., HPD said a woman's body was found in White Oak Bayou near North Main Street.
It's unclear how the two victims died. Officials did not provide additional information about either of the investigations underway.
The identity and cause of death of the man and woman are pending verification by the Harris County Institute of Forensic Sciences.
Anyone with information in either case is urged to contact the HPD Homicide Division at 713-308-3600.
