Police probing Sherman murders learned of mysterious suspect with odd walk almost four years ago
''Police provided a third timeline, this one for the mystery person. According to the newly released documents, police have at least 20 video stills or videos from neighbourhood cameras showing this person.
Police were particularly interested in what they describe as an odd “gait” — the person kicks up the back of the right heel with each step. Some doctors contacted the Star to say this is “drop foot,” caused by a neurological condition.''
fwiw..
Foot drop - Symptoms and causes
''Foot drop, sometimes called drop foot, is a general term for difficulty lifting the front part of the foot. If you have foot drop, the front of your foot might drag on the ground when you walk.
Foot drop isn't a disease. Rather,
foot drop is a sign of an underlying neurological, muscular or anatomical problem.
Sometimes foot drop is temporary, but it can be permanent. If you have foot drop, you might need to wear a brace on your ankle and foot to hold your foot in a normal position''
''Foot drop makes it difficult to lift the front part of your foot, so it might drag on the floor when you walk. This can cause you to raise your thigh when you walk, as though climbing stairs (steppage gait), to help your foot clear the floor. This unusual gait might cause you to slap your foot down onto the floor with each step. In some cases, the skin on the top of your foot and toes feels numb.
Depending on the cause, foot drop can affect one or both feet.''
